-.Sh NAME
-.Nm fnmatch
-.Nd match filename or pathname
-.Sh LIBRARY
-.Lb libc
-.Sh SYNOPSIS
-.In fnmatch.h
-.Ft int
-.Fn fnmatch "const char *pattern" "const char *string" "int flags"
-.Sh DESCRIPTION
-The
-.Fn fnmatch
-function
-matches patterns according to the rules used by the shell.
-It checks the string specified by the
-.Fa string
-argument to see if it matches the pattern specified by the
-.Fa pattern
-argument.
-.Pp
-The
-.Fa flags
-argument modifies the interpretation of
-.Fa pattern
-and
-.Fa string .
-The value of
-.Fa flags
-is the bitwise inclusive
-.Tn OR
-of any of the following
-constants, which are defined in the include file
-.Pa fnmatch.h .
-.Bl -tag -width FNM_PATHNAME
-.It Dv FNM_NOESCAPE
-Normally, every occurrence of a backslash
-.Pq Ql \e
-followed by a character in
-.Fa pattern
-is replaced by that character.
-This is done to negate any special meaning for the character.
-If the
-.Dv FNM_NOESCAPE
-flag is set, a backslash character is treated as an ordinary character.
-.It Dv FNM_PATHNAME
-Slash characters in
-.Fa string
-must be explicitly matched by slashes in
-.Fa pattern .
-If this flag is not set, then slashes are treated as regular characters.
-.It Dv FNM_PERIOD
-Leading periods in
-.Fa string
-must be explicitly matched by periods in
-.Fa pattern .
-If this flag is not set, then leading periods are treated as regular
-characters.
-The definition of
-.Dq leading
-is related to the specification of
-.Dv FNM_PATHNAME .
-A period is always
-.Dq leading
-if it is the first character in
-.Ar string .
-Additionally, if
-.Dv FNM_PATHNAME
-is set,
-a period is
-leading
-if it immediately follows a slash.
-.It Dv FNM_LEADING_DIR
-Ignore
-.Nm /*
-rest after successful
-.Fa pattern
-matching.
-.It Dv FNM_CASEFOLD
-Ignore  case  distinctions in both the
-.Fa pattern
-and the
-.Fa string .
-.El
-.Sh RETURN VALUES
-The
-.Fn fnmatch
-function returns zero if
-.Fa string
-matches the pattern specified by
-.Fa pattern ,
-otherwise, it returns the value
-.Dv FNM_NOMATCH .
-.Sh SEE ALSO
-.Xr sh 1 ,
-.Xr glob 3 ,
-.Xr regex 3
-.Sh STANDARDS
-The
-.Fn fnmatch
-function conforms to
-.St -p1003.2 .
-.Sh HISTORY
-The
-.Fn fnmatch
-function first appeared in
-.Bx 4.4 .
-.Sh BUGS
-The pattern
-.Ql *
-matches the empty string, even if
-.Dv FNM_PATHNAME
-is specified.

-.Sh NAME
-.Nm glob ,
-.Nm globfree
-.Nd generate pathnames matching a pattern
-.Sh LIBRARY
-.Lb libc
-.Sh SYNOPSIS
-.In glob.h
-.Ft int
-.Fn glob "const char *pattern" "int flags" "int (*errfunc)(const char *, int)" "glob_t *pglob"
-.Ft void
-.Fn globfree "glob_t *pglob"
-.Sh DESCRIPTION
-The
-.Fn glob
-function
-is a pathname generator that implements the rules for file name pattern
-matching used by the shell.
-.Pp
-The include file
-.Pa glob.h
-defines the structure type
-.Fa glob_t ,
-which contains at least the following fields:
-.Bd -literal
-typedef struct {
-	int gl_pathc;		/* count of total paths so far */
-	int gl_matchc;		/* count of paths matching pattern */
-	int gl_offs;		/* reserved at beginning of gl_pathv */
-	int gl_flags;		/* returned flags */
-	char **gl_pathv;	/* list of paths matching pattern */
-} glob_t;
-.Ed
-.Pp
-The argument
-.Fa pattern
-is a pointer to a pathname pattern to be expanded.
-The
-.Fn glob
-argument
-matches all accessible pathnames against the pattern and creates
-a list of the pathnames that match.
-In order to have access to a pathname,
-.Fn glob
-requires search permission on every component of a path except the last
-and read permission on each directory of any filename component of
-.Fa pattern
-that contains any of the special characters
-.Ql * ,
-.Ql ?\&
-or
-.Ql \&[ .
-.Pp
-The
-.Fn glob
-argument
-stores the number of matched pathnames into the
-.Fa gl_pathc
-field, and a pointer to a list of pointers to pathnames into the
-.Fa gl_pathv
-field.
-The first pointer after the last pathname is
-.Dv NULL .
-If the pattern does not match any pathnames, the returned number of
-matched paths is set to zero.
-.Pp
-It is the caller's responsibility to create the structure pointed to by
-.Fa pglob .
-The
-.Fn glob
-function allocates other space as needed, including the memory pointed
-to by
-.Fa gl_pathv .
-.Pp
-The argument
-.Fa flags
-is used to modify the behavior of
-.Fn glob .
-The value of
-.Fa flags
-is the bitwise inclusive
-.Tn OR
-of any of the following
-values defined in
-.Pa glob.h :
-.Bl -tag -width GLOB_ALTDIRFUNC
-.It Dv GLOB_APPEND
-Append pathnames generated to the ones from a previous call (or calls)
-to
-.Fn glob .
-The value of
-.Fa gl_pathc
-will be the total matches found by this call and the previous call(s).
-The pathnames are appended to, not merged with the pathnames returned by
-the previous call(s).
-Between calls, the caller must not change the setting of the
-.Dv GLOB_DOOFFS
-flag, nor change the value of
-.Fa gl_offs
-when
-.Dv GLOB_DOOFFS
-is set, nor (obviously) call
-.Fn globfree
-for
-.Fa pglob .
-.It Dv GLOB_DOOFFS
-Make use of the
-.Fa gl_offs
-field.
-If this flag is set,
-.Fa gl_offs
-is used to specify how many
-.Dv NULL
-pointers to prepend to the beginning
-of the
-.Fa gl_pathv
-field.
-In other words,
-.Fa gl_pathv
-will point to
-.Fa gl_offs
-.Dv NULL
-pointers,
-followed by
-.Fa gl_pathc
-pathname pointers, followed by a
-.Dv NULL
-pointer.
-.It Dv GLOB_ERR
-Causes
-.Fn glob
-to return when it encounters a directory that it cannot open or read.
-Ordinarily,
-.Fn glob
-continues to find matches.
-.It Dv GLOB_MARK
-Each pathname that is a directory that matches
-.Fa pattern
-has a slash
-appended.
-.It Dv GLOB_NOCHECK
-If
-.Fa pattern
-does not match any pathname, then
-.Fn glob
-returns a list
-consisting of only
-.Fa pattern ,
-with the number of total pathnames is set to 1, and the number of matched
-pathnames set to 0.
-If
-.Dv GLOB_QUOTE
-is set, its effect is present in the pattern returned.
-.It Dv GLOB_NOSORT
-By default, the pathnames are sorted in ascending
-.Tn ASCII
-order;
-this flag prevents that sorting (speeding up
-.Fn glob ) .
-.El
-.Pp
-The following values may also be included in
-.Fa flags ,
-however, they are non-standard extensions to
-.St -p1003.2 .
-.Bl -tag -width GLOB_ALTDIRFUNC
-.It Dv GLOB_ALTDIRFUNC
-The following additional fields in the pglob structure have been
-initialized with alternate functions for glob to use to open, read,
-and close directories and to get stat information on names found
-in those directories.
-.Bd -literal
-void *(*gl_opendir)(const char * name);
-struct dirent *(*gl_readdir)(void *);
-void (*gl_closedir)(void *);
-int (*gl_lstat)(const char *name, struct stat *st);
-int (*gl_stat)(const char *name, struct stat *st);
-.Ed
-.Pp
-This extension is provided to allow programs such as
-.Xr restore 8
-to provide globbing from directories stored on tape.
-.It Dv GLOB_BRACE
-Pre-process the pattern string to expand
-.Ql {pat,pat,...}
-strings like
-.Xr csh 1 .
-The pattern
-.Ql {}
-is left unexpanded for historical reasons (and
-.Xr csh 1
-does the same thing to
-ease typing
-of
-.Xr find 1
-patterns).
-.It Dv GLOB_MAGCHAR
-Set by the
-.Fn glob
-function if the pattern included globbing characters.
-See the description of the usage of the
-.Fa gl_matchc
-structure member for more details.
-.It Dv GLOB_NOMAGIC
-Is the same as
-.Dv GLOB_NOCHECK
-but it only appends the
-.Fa pattern
-if it does not contain any of the special characters ``*'', ``?'' or ``[''.
-.Dv GLOB_NOMAGIC
-is provided to simplify implementing the historic
-.Xr csh 1
-globbing behavior and should probably not be used anywhere else.
-.It Dv GLOB_QUOTE
-Use the backslash
-.Pq Ql \e
-character for quoting: every occurrence of
-a backslash followed by a character in the pattern is replaced by that
-character, avoiding any special interpretation of the character.
-.It Dv GLOB_TILDE
-Expand patterns that start with
-.Ql ~
-to user name home directories.
-.It Dv GLOB_LIMIT
-Limit the total number of returned pathnames to the value provided in
-.Fa gl_matchc
-(default
-.Dv ARG_MAX ) .
-This option should be set for programs
-that can be coerced into a denial of service attack
-via patterns that expand to a very large number of matches,
-such as a long string of
-.Ql */../*/.. .
-.El
-.Pp
-If, during the search, a directory is encountered that cannot be opened
-or read and
-.Fa errfunc
-is
-.Pf non- Dv NULL ,
-.Fn glob
-calls
-.Fa \*(lp*errfunc\*(rp Ns ( Fa path , errno ) .
-This may be unintuitive: a pattern like
-.Ql */Makefile
-will try to
-.Xr stat 2
-.Ql foo/Makefile
-even if
-.Ql foo
-is not a directory, resulting in a
-call to
-.Fa errfunc .
-The error routine can suppress this action by testing for
-.Er ENOENT
-and
-.Er ENOTDIR ;
-however, the
-.Dv GLOB_ERR
-flag will still cause an immediate
-return when this happens.
-.Pp
-If
-.Fa errfunc
-returns non-zero,
-.Fn glob
-stops the scan and returns
-.Dv GLOB_ABEND
-after setting
-.Fa gl_pathc
-and
-.Fa gl_pathv
-to reflect any paths already matched.
-This also happens if an error is encountered and
-.Dv GLOB_ERR
-is set in
-.Fa flags ,
-regardless of the return value of
-.Fa errfunc ,
-if called.
-If
-.Dv GLOB_ERR
-is not set and either
-.Fa errfunc
-is
-.Dv NULL
-or
-.Fa errfunc
-returns zero, the error is ignored.
-.Pp
-The
-.Fn globfree
-function frees any space associated with
-.Fa pglob
-from a previous call(s) to
-.Fn glob .

-On successful completion,
-.Fn glob
-returns zero.
-In addition the fields of
-.Fa pglob
-contain the values described below:
-.Bl -tag -width GLOB_NOCHECK
-.It Fa gl_pathc
-contains the total number of matched pathnames so far.
-This includes other matches from previous invocations of
-.Fn glob
-if
-.Dv GLOB_APPEND
-was specified.
-.It Fa gl_matchc
-contains the number of matched pathnames in the current invocation of
-.Fn glob .
-.It Fa gl_flags
-contains a copy of the
-.Fa flags
-parameter with the bit
-.Dv GLOB_MAGCHAR
-set if
-.Fa pattern
-contained any of the special characters ``*'', ``?'' or ``['', cleared
-if not.
-.It Fa gl_pathv
-contains a pointer to a
-.Dv NULL Ns -terminated
-list of matched pathnames.
-However, if
-.Fa gl_pathc
-is zero, the contents of
-.Fa gl_pathv
-are undefined.
-.El
-.Pp
-If
-.Fn glob
-terminates due to an error, it sets errno and returns one of the
-following non-zero constants, which are defined in the include
-file
-.Aq Pa glob.h :
-.Bl -tag -width GLOB_NOCHECK
-.It Dv GLOB_NOSPACE
-An attempt to allocate memory failed, or if
-.Fa errno
-was 0
-.Dv GLOB_LIMIT
-was specified in the flags and
-.Fa pglob\->gl_matchc
-or more patterns were matched.
-.It Dv GLOB_ABEND
-The scan was stopped because an error was encountered and either
-.Dv GLOB_ERR
-was set or
-.Fa \*(lp*errfunc\*(rp\*(lp\*(rp
-returned non-zero.
-.El
-.Pp
-The arguments
-.Fa pglob\->gl_pathc
-and
-.Fa pglob\->gl_pathv
-are still set as specified above.
-.Sh EXAMPLES
-A rough equivalent of
-.Ql "ls -l *.c *.h"
-can be obtained with the
-following code:
-.Bd -literal -offset indent
-glob_t g;
-
-g.gl_offs = 2;
-glob("*.c", GLOB_DOOFFS, NULL, &g);
-glob("*.h", GLOB_DOOFFS | GLOB_APPEND, NULL, &g);
-g.gl_pathv[0] = "ls";
-g.gl_pathv[1] = "-l";
-execvp("ls", g.gl_pathv);
-.Ed
-.Sh SEE ALSO
-.Xr sh 1 ,
-.Xr fnmatch 3 ,
-.Xr regexp 3
-.Sh STANDARDS
-The
-.Fn glob
-function is expected to be
-.St -p1003.2
-compatible with the exception
-that the flags
-.Dv GLOB_ALTDIRFUNC ,
-.Dv GLOB_BRACE ,
-.Dv GLOB_LIMIT ,
-.Dv GLOB_MAGCHAR ,
-.Dv GLOB_NOMAGIC ,
-.Dv GLOB_QUOTE ,
-and
-.Dv GLOB_TILDE ,
-and the fields
-.Fa gl_matchc
-and
-.Fa gl_flags
-should not be used by applications striving for strict
-.Tn POSIX
-conformance.
-.Sh HISTORY
-The
-.Fn glob
-and
-.Fn globfree
-functions first appeared in
-.Bx 4.4 .
-.Sh BUGS
-Patterns longer than
-.Dv MAXPATHLEN
-may cause unchecked errors.
-.Pp
-The
-.Fn glob
-argument
-may fail and set errno for any of the errors specified for the
-library routines
-.Xr stat 2 ,
-.Xr closedir 3 ,
-.Xr opendir 3 ,
-.Xr readdir 3 ,
-.Xr malloc 3 ,
-and
-.Xr free 3 .

-FUNCTION
-<<popen>>, <<pclose>>---tie a stream to a command string
-
-INDEX
-	popen
-INDEX
-	pclose
-
-ANSI_SYNOPSIS
-	#include <stdio.h>
-	FILE *popen(const char *<[s]>, const char *<[mode]>);
-
-	int pclose(FILE *<[f]>);
-
-DESCRIPTION
-Use <<popen>> to create a stream to a child process executing a
-command string <<*<[s]>>> as processed by <</bin/sh>> on your system.
-The argument <[mode]> must start with either `<<r>>', where the stream
-reads from the child's <<stdout>>, or `<<w>>', where the stream writes
-to the child's <<stdin>>.  As an extension, <[mode]> may also contain
-`<<e>>' to set the close-on-exec bit of the parent's file descriptor.
-The stream created by <<popen>> must be closed by <<pclose>> to avoid
-resource leaks.
-
-Streams created by prior calls to <<popen>> are not visible in
-subsequent <<popen>> children, regardless of the close-on-exec bit.
-
-Use ``<<system(NULL)>>'' to test whether your system has <</bin/sh>>
-available.
-
-RETURNS
-<<popen>> returns a file stream opened with the specified <[mode]>,
-or <<NULL>> if a child process could not be created.  <<pclose>>
-returns -1 if the stream was not created by <<popen>> or if the
-application used <<wait>> or similar to steal the status; otherwise
-it returns the exit status of the child which can be interpreted
-in the same manner as a status obtained by <<waitpid>>.
-
-PORTABILITY
-POSIX.2 requires <<popen>> and <<pclose>>, but only specifies a mode
-of just <<r>> or <<w>>.  Where <<sh>> is found is left unspecified.
-
-Supporting OS subroutines required: <<_exit>>, <<_execve>>, <<_fork_r>>,
-<<_wait_r>>, <<pipe>>, <<fcntl>>, <<sbrk>>.

-.Fc
-.Ft void
-.Fn regfree "regex_t *preg"
-.Sh DESCRIPTION
-These routines implement
-.St -p1003.2
-regular expressions
-.Pq Do RE Dc Ns s ;
-see
-.Xr re_format 7 .
-.Fn Regcomp
-compiles an RE written as a string into an internal form,
-.Fn regexec
-matches that internal form against a string and reports results,
-.Fn regerror
-transforms error codes from either into human-readable messages,
-and
-.Fn regfree
-frees any dynamically-allocated storage used by the internal form
-of an RE.
-.Pp
-The header
-.Aq Pa regex.h
-declares two structure types,
-.Ft regex_t
-and
-.Ft regmatch_t ,
-the former for compiled internal forms and the latter for match reporting.
-It also declares the four functions,
-a type
-.Ft regoff_t ,
-and a number of constants with names starting with
-.Dq Dv REG_ .
-.Pp
-.Fn Regcomp
-compiles the regular expression contained in the
-.Fa pattern
-string,
-subject to the flags in
-.Fa cflags ,
-and places the results in the
-.Ft regex_t
-structure pointed to by
-.Fa preg .
-.Fa Cflags
-is the bitwise OR of zero or more of the following flags:
-.Bl -tag -width REG_EXTENDED
-.It Dv REG_EXTENDED
-Compile modern
-.Pq Dq extended
-REs,
-rather than the obsolete
-.Pq Dq basic
-REs that
-are the default.
-.It Dv REG_BASIC
-This is a synonym for 0,
-provided as a counterpart to
-.Dv REG_EXTENDED
-to improve readability.
-.It Dv REG_NOSPEC
-Compile with recognition of all special characters turned off.
-All characters are thus considered ordinary,
-so the
-.Dq RE
-is a literal string.
-This is an extension,
-compatible with but not specified by
-.St -p1003.2 ,
-and should be used with
-caution in software intended to be portable to other systems.
-.Dv REG_EXTENDED
-and
-.Dv REG_NOSPEC
-may not be used
-in the same call to
-.Fn regcomp .
-.It Dv REG_ICASE
-Compile for matching that ignores upper/lower case distinctions.
-See
-.Xr re_format 7 .
-.It Dv REG_NOSUB
-Compile for matching that need only report success or failure,
-not what was matched.
-.It Dv REG_NEWLINE
-Compile for newline-sensitive matching.
-By default, newline is a completely ordinary character with no special
-meaning in either REs or strings.
-With this flag,
-.Ql [^
-bracket expressions and
-.Ql .\&
-never match newline,
-a
-.Ql ^\&
-anchor matches the null string after any newline in the string
-in addition to its normal function,
-and the
-.Ql $\&
-anchor matches the null string before any newline in the
-string in addition to its normal function.
-.It Dv REG_PEND
-The regular expression ends,
-not at the first NUL,
-but just before the character pointed to by the
-.Va re_endp
-member of the structure pointed to by
-.Fa preg .
-The
-.Va re_endp
-member is of type
-.Ft "const char *" .
-This flag permits inclusion of NULs in the RE;
-they are considered ordinary characters.
-This is an extension,
-compatible with but not specified by
-.St -p1003.2 ,
-and should be used with
-caution in software intended to be portable to other systems.
-.El
-.Pp
-When successful,
-.Fn regcomp
-returns 0 and fills in the structure pointed to by
-.Fa preg .
-One member of that structure
-(other than
-.Va re_endp )
-is publicized:
-.Va re_nsub ,
-of type
-.Ft size_t ,
-contains the number of parenthesized subexpressions within the RE
-(except that the value of this member is undefined if the
-.Dv REG_NOSUB
-flag was used).
-If
-.Fn regcomp
-fails, it returns a non-zero error code;
-see
-.Sx DIAGNOSTICS .
-.Pp
-.Fn Regexec
-matches the compiled RE pointed to by
-.Fa preg
-against the
-.Fa string ,
-subject to the flags in
-.Fa eflags ,
-and reports results using
-.Fa nmatch ,
-.Fa pmatch ,
-and the returned value.
-The RE must have been compiled by a previous invocation of
-.Fn regcomp .
-The compiled form is not altered during execution of
-.Fn regexec ,
-so a single compiled RE can be used simultaneously by multiple threads.
-.Pp
-By default,
-the NUL-terminated string pointed to by
-.Fa string
-is considered to be the text of an entire line, minus any terminating
-newline.
-The
-.Fa eflags
-argument is the bitwise OR of zero or more of the following flags:
-.Bl -tag -width REG_STARTEND
-.It Dv REG_NOTBOL
-The first character of
-the string
-is not the beginning of a line, so the
-.Ql ^\&
-anchor should not match before it.
-This does not affect the behavior of newlines under
-.Dv REG_NEWLINE .
-.It Dv REG_NOTEOL
-The NUL terminating
-the string
-does not end a line, so the
-.Ql $\&
-anchor should not match before it.
-This does not affect the behavior of newlines under
-.Dv REG_NEWLINE .
-.It Dv REG_STARTEND
-The string is considered to start at
-.Fa string
-+
-.Fa pmatch Ns [0]. Ns Va rm_so
-and to have a terminating NUL located at
-.Fa string
-+
-.Fa pmatch Ns [0]. Ns Va rm_eo
-(there need not actually be a NUL at that location),
-regardless of the value of
-.Fa nmatch .
-See below for the definition of
-.Fa pmatch
-and
-.Fa nmatch .
-This is an extension,
-compatible with but not specified by
-.St -p1003.2 ,
-and should be used with
-caution in software intended to be portable to other systems.
-Note that a non-zero
-.Va rm_so
-does not imply
-.Dv REG_NOTBOL ;
-.Dv REG_STARTEND
-affects only the location of the string,
-not how it is matched.
-.El
-.Pp
-See
-.Xr re_format 7
-for a discussion of what is matched in situations where an RE or a
-portion thereof could match any of several substrings of
-.Fa string .
-.Pp
-Normally,
-.Fn regexec
-returns 0 for success and the non-zero code
-.Dv REG_NOMATCH
-for failure.
-Other non-zero error codes may be returned in exceptional situations;
-see
-.Sx DIAGNOSTICS .
-.Pp
-If
-.Dv REG_NOSUB
-was specified in the compilation of the RE,
-or if
-.Fa nmatch
-is 0,
-.Fn regexec
-ignores the
-.Fa pmatch
-argument (but see below for the case where
-.Dv REG_STARTEND
-is specified).
-Otherwise,
-.Fa pmatch
-points to an array of
-.Fa nmatch
-structures of type
-.Ft regmatch_t .
-Such a structure has at least the members
-.Va rm_so
-and
-.Va rm_eo ,
-both of type
-.Ft regoff_t
-(a signed arithmetic type at least as large as an
-.Ft off_t
-and a
-.Ft ssize_t ) ,
-containing respectively the offset of the first character of a substring
-and the offset of the first character after the end of the substring.
-Offsets are measured from the beginning of the
-.Fa string
-argument given to
-.Fn regexec .
-An empty substring is denoted by equal offsets,
-both indicating the character following the empty substring.
-.Pp
-The 0th member of the
-.Fa pmatch
-array is filled in to indicate what substring of
-.Fa string
-was matched by the entire RE.
-Remaining members report what substring was matched by parenthesized
-subexpressions within the RE;
-member
-.Va i
-reports subexpression
-.Va i ,
-with subexpressions counted (starting at 1) by the order of their opening
-parentheses in the RE, left to right.
-Unused entries in the array (corresponding either to subexpressions that
-did not participate in the match at all, or to subexpressions that do not
-exist in the RE (that is,
-.Va i
->
-.Fa preg Ns -> Ns Va re_nsub ) )
-have both
-.Va rm_so
-and
-.Va rm_eo
-set to -1.
-If a subexpression participated in the match several times,
-the reported substring is the last one it matched.
-(Note, as an example in particular, that when the RE
-.Ql "(b*)+"
-matches
-.Ql bbb ,
-the parenthesized subexpression matches each of the three
-.So Li b Sc Ns s
-and then
-an infinite number of empty strings following the last
-.Ql b ,
-so the reported substring is one of the empties.)
-.Pp
-If
-.Dv REG_STARTEND
-is specified,
-.Fa pmatch
-must point to at least one
-.Ft regmatch_t
-(even if
-.Fa nmatch
-is 0 or
-.Dv REG_NOSUB
-was specified),
-to hold the input offsets for
-.Dv REG_STARTEND .
-Use for output is still entirely controlled by
-.Fa nmatch ;
-if
-.Fa nmatch
-is 0 or
-.Dv REG_NOSUB
-was specified,
-the value of
-.Fa pmatch Ns [0]
-will not be changed by a successful
-.Fn regexec .
-.Pp
-.Fn Regerror
-maps a non-zero
-.Fa errcode
-from either
-.Fn regcomp
-or
-.Fn regexec
-to a human-readable, printable message.
-If
-.Fa preg
-is
-.No non\- Ns Dv NULL ,
-the error code should have arisen from use of
-the
-.Ft regex_t
-pointed to by
-.Fa preg ,
-and if the error code came from
-.Fn regcomp ,
-it should have been the result from the most recent
-.Fn regcomp
-using that
-.Ft regex_t .
-.No ( Fn Regerror
-may be able to supply a more detailed message using information
-from the
-.Ft regex_t . )
-.Fn Regerror
-places the NUL-terminated message into the buffer pointed to by
-.Fa errbuf ,
-limiting the length (including the NUL) to at most
-.Fa errbuf_size
-bytes.
-If the whole message won't fit,
-as much of it as will fit before the terminating NUL is supplied.
-In any case,
-the returned value is the size of buffer needed to hold the whole
-message (including terminating NUL).
-If
-.Fa errbuf_size
-is 0,
-.Fa errbuf
-is ignored but the return value is still correct.
-.Pp
-If the
-.Fa errcode
-given to
-.Fn regerror
-is first ORed with
-.Dv REG_ITOA ,
-the
-.Dq message
-that results is the printable name of the error code,
-e.g.\&
-.Dq Dv REG_NOMATCH ,
-rather than an explanation thereof.
-If
-.Fa errcode
-is
-.Dv REG_ATOI ,
-then
-.Fa preg
-shall be
-.No non\- Ns Dv NULL
-and the
-.Va re_endp
-member of the structure it points to
-must point to the printable name of an error code;
-in this case, the result in
-.Fa errbuf
-is the decimal digits of
-the numeric value of the error code
-(0 if the name is not recognized).
-.Dv REG_ITOA
-and
-.Dv REG_ATOI
-are intended primarily as debugging facilities;
-they are extensions,
-compatible with but not specified by
-.St -p1003.2 ,
-and should be used with
-caution in software intended to be portable to other systems.
-Be warned also that they are considered experimental and changes are possible.
-.Pp
-.Fn Regfree
-frees any dynamically-allocated storage associated with the compiled RE
-pointed to by
-.Fa preg .
-The remaining
-.Ft regex_t
-is no longer a valid compiled RE
-and the effect of supplying it to
-.Fn regexec
-or
-.Fn regerror
-is undefined.
-.Pp
-None of these functions references global variables except for tables
-of constants;
-all are safe for use from multiple threads if the arguments are safe.
-.Sh IMPLEMENTATION CHOICES
-There are a number of decisions that
-.St -p1003.2
-leaves up to the implementor,
-either by explicitly saying
-.Dq undefined
-or by virtue of them being
-forbidden by the RE grammar.
-This implementation treats them as follows.
-.Pp
-See
-.Xr re_format 7
-for a discussion of the definition of case-independent matching.
-.Pp
-There is no particular limit on the length of REs,
-except insofar as memory is limited.
-Memory usage is approximately linear in RE size, and largely insensitive
-to RE complexity, except for bounded repetitions.
-See
-.Sx BUGS
-for one short RE using them
-that will run almost any system out of memory.
-.Pp
-A backslashed character other than one specifically given a magic meaning
-by
-.St -p1003.2
-(such magic meanings occur only in obsolete
-.Bq Dq basic
-REs)
-is taken as an ordinary character.
-.Pp
-Any unmatched
-.Ql [\&
-is a
-.Dv REG_EBRACK
-error.
-.Pp
-Equivalence classes cannot begin or end bracket-expression ranges.
-The endpoint of one range cannot begin another.
-.Pp
-.Dv RE_DUP_MAX ,
-the limit on repetition counts in bounded repetitions, is 255.
-.Pp
-A repetition operator
-.Ql ( ?\& ,
-.Ql *\& ,
-.Ql +\& ,
-or bounds)
-cannot follow another
-repetition operator.
-A repetition operator cannot begin an expression or subexpression
-or follow
-.Ql ^\&
-or
-.Ql |\& .
-.Pp
-.Ql |\&
-cannot appear first or last in a (sub)expression or after another
-.Ql |\& ,
-i.e. an operand of
-.Ql |\&
-cannot be an empty subexpression.
-An empty parenthesized subexpression,
-.Ql "()" ,
-is legal and matches an
-empty (sub)string.
-An empty string is not a legal RE.
-.Pp
-A
-.Ql {\&
-followed by a digit is considered the beginning of bounds for a
-bounded repetition, which must then follow the syntax for bounds.
-A
-.Ql {\&
-.Em not
-followed by a digit is considered an ordinary character.
-.Pp
-.Ql ^\&
-and
-.Ql $\&
-beginning and ending subexpressions in obsolete
-.Pq Dq basic
-REs are anchors, not ordinary characters.

-.Sh HISTORY
-Originally written by
-.An Henry Spencer .
-Altered for inclusion in the
-.Bx 4.4
-distribution.
-.Sh BUGS
-This is an alpha release with known defects.
-Please report problems.
-.Pp
-The back-reference code is subtle and doubts linger about its correctness
-in complex cases.
-.Pp
-.Fn Regexec
-performance is poor.
-This will improve with later releases.
-.Fa Nmatch
-exceeding 0 is expensive;
-.Fa nmatch
-exceeding 1 is worse.
-.Fn Regexec
-is largely insensitive to RE complexity
-.Em except
-that back
-references are massively expensive.
-RE length does matter; in particular, there is a strong speed bonus
-for keeping RE length under about 30 characters,
-with most special characters counting roughly double.
-.Pp
-.Fn Regcomp
-implements bounded repetitions by macro expansion,
-which is costly in time and space if counts are large
-or bounded repetitions are nested.
-An RE like, say,
-.Ql "((((a{1,100}){1,100}){1,100}){1,100}){1,100}"
-will (eventually) run almost any existing machine out of swap space.
-.Pp
-There are suspected problems with response to obscure error conditions.
-Notably,
-certain kinds of internal overflow,
-produced only by truly enormous REs or by multiply nested bounded repetitions,
-are probably not handled well.
-.Pp
-Due to a mistake in
-.St -p1003.2 ,
-things like
-.Ql "a)b"
-are legal REs because
-.Ql )\&
-is
-a special character only in the presence of a previous unmatched
-.Ql (\& .
-This can't be fixed until the spec is fixed.
-.Pp
-The standard's definition of back references is vague.
-For example, does
-.Ql "a\e(\e(b\e)*\e2\e)*d"
-match
-.Ql "abbbd" ?
-Until the standard is clarified,
-behavior in such cases should not be relied on.
-.Pp
-The implementation of word-boundary matching is a bit of a kludge,
-and bugs may lurk in combinations of word-boundary matching and anchoring.

- *  SYSEXITS.H -- Exit status codes for system programs.
- *
- *	This include file attempts to categorize possible error
- *	exit statuses for system programs, notably delivermail
- *	and the Berkeley network.
- *
- *	Error numbers begin at EX__BASE to reduce the possibility of
- *	clashing with other exit statuses that random programs may
- *	already return.  The meaning of the codes is approximately
- *	as follows:
- *
- *	EX_USAGE -- The command was used incorrectly, e.g., with
- *		the wrong number of arguments, a bad flag, a bad
- *		syntax in a parameter, or whatever.
- *	EX_DATAERR -- The input data was incorrect in some way.
- *		This should only be used for user's data & not
- *		system files.
- *	EX_NOINPUT -- An input file (not a system file) did not
- *		exist or was not readable.  This could also include
- *		errors like "No message" to a mailer (if it cared
- *		to catch it).
- *	EX_NOUSER -- The user specified did not exist.  This might
- *		be used for mail addresses or remote logins.
- *	EX_NOHOST -- The host specified did not exist.  This is used
- *		in mail addresses or network requests.
- *	EX_UNAVAILABLE -- A service is unavailable.  This can occur
- *		if a support program or file does not exist.  This
- *		can also be used as a catchall message when something
- *		you wanted to do doesn't work, but you don't know
- *		why.
- *	EX_SOFTWARE -- An internal software error has been detected.
- *		This should be limited to non-operating system related
- *		errors as possible.
- *	EX_OSERR -- An operating system error has been detected.
- *		This is intended to be used for such things as "cannot
- *		fork", "cannot create pipe", or the like.  It includes
- *		things like getuid returning a user that does not
- *		exist in the passwd file.
- *	EX_OSFILE -- Some system file (e.g., /etc/passwd, /etc/utmp,
- *		etc.) does not exist, cannot be opened, or has some
- *		sort of error (e.g., syntax error).
- *	EX_CANTCREAT -- A (user specified) output file cannot be
- *		created.
- *	EX_IOERR -- An error occurred while doing I/O on some file.
- *	EX_TEMPFAIL -- temporary failure, indicating something that
- *		is not really an error.  In sendmail, this means
- *		that a mailer (e.g.) could not create a connection,
- *		and the request should be reattempted later.
- *	EX_PROTOCOL -- the remote system returned something that
- *		was "not possible" during a protocol exchange.
- *	EX_NOPERM -- You did not have sufficient permission to
- *		perform the operation.  This is not intended for
- *		file system problems, which should use NOINPUT or
- *		CANTCREAT, but rather for higher level permissions.
