From 5bc584ba65db809b22dd2e10eb2cef922ca60d26 Mon Sep 17 00:00:00 2001 From: Christopher Faylor Date: Mon, 17 Jul 2000 19:18:21 +0000 Subject: Throughout, eliminate third argument to path_conv and use new PC_* constants for second argument. * path.h: Generalize SYMLINK_* constants to PC_*. (path_conv): Create a new method. Fold third argument into second. * dll_init.cc (dll_list::alloc): Try harder to find space to allocate dll struct. (dll_dllcrt0): Don't check sanity if we've already called dll_crt0. * path.cc (path_conv::check): Don't check for a null or empty path unless specifically told with a flag setting. (check_null_empty_path): New function, adapted from macro. * syscalls.cc (_rename): Use already-determined file attributes rather than checking again. * lib/cygwin/cygwin_attach.dll.c (cygwin_attach_dll): Use a static per_process structure since this is apparently supposed to be zeroed. * lib/cygwin_crt0.c (cygwin_crt0): Zero per_process structure sent to older DLLs. --- winsup/cygwin/environ.cc | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) (limited to 'winsup/cygwin/environ.cc') diff --git a/winsup/cygwin/environ.cc b/winsup/cygwin/environ.cc index b53600724..7c236df42 100644 --- a/winsup/cygwin/environ.cc +++ b/winsup/cygwin/environ.cc @@ -259,12 +259,13 @@ setenv (const char *name, const char *value, int rewrite) extern "C" void unsetenv (const char *name) { - register char **P; + register char **e; int offset; while (my_findenv (name, &offset)) /* if set multiple times */ - for (P = &environ[offset];; ++P) - if (!(*P = *(P + 1))) + /* Move up the rest of the array */ + for (e = environ + offset; ; e++) + if (!(*e = *(e + 1))) break; } -- cgit v1.2.3
