+FUNCTION
+<<sniprintf>>---write formatted output (integer only)
+
+INDEX
+ sniprintf
+
+ANSI_SYNOPSIS
+ #include <stdio.h>
+
+ int sniprintf(char *<[str]>, size_t <[size]>, const char *<[format]> [, <[arg]>, ...]);
+
+TRAD_SYNOPSIS
+ #include <stdio.h>
+
+ int sniprintf(<[str]>, size_t <[size]>, <[format]> [, <[arg]>, ...]);
+ char *<[str]>;
+ size_t <[size]>;
+ char *<[format]>;
+
+DESCRIPTION
+<<sniprintf>> is a restricted version of <<snprintf>>: it has the same
+arguments and behavior, save that it cannot perform any floating-point
+formatting: the <<f>>, <<g>>, <<G>>, <<e>>, and <<F>> type specifiers
+are not recognized.
+
+RETURNS
+ <<sniprintf>> returns the number of bytes in the output string,
+ save that the concluding <<NULL>> is not counted.
+ <<sniprintf>> returns when the end of the format string is
+ encountered.
+
+PORTABILITY
+<<sniprintf>> is not required by ANSI C.
+
+Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
+<<lseek>>, <<read>>, <<sbrk>>, <<write>>.
