* getgroups: don't expose GETGROUPS_T to userEric Blake2009-11-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These days, most systems already declare getgroups with gid_t*. But in the rare case that GETGROUPS_T is still int but gid_t is short, the user should not have to uglify their code; let the replacement hide all the magic. Tested by configuring with ac_cv_type_getgroups=uint64_t on a platform with 32-bit gid_t, and ignoring compiler warnings. However, since we don't replace setgroups, the GETGROUPS_T workaround is still needed there for now. * lib/getgroups.c (rpl_getgroups): Change signature. Copy array an element at a time if GETGROUPS_T is wrong size. * lib/getugroups.h (getugroups): Change signature. * lib/unistd.in.h (getgroups): Likewise. * m4/getgroups.m4 (gl_FUNC_GETGROUPS): Use replacement if signature needs fixing. * m4/getugroups.m4 (gl_GETUGROUPS): No longer need AC_TYPE_GETGROUPS. * modules/group-member (Depends-on): Add getgroups. * lib/group-member.c (group_info, get_group_info): Use gid_t. (group_member): Rely on getgroups replacement. * lib/getugroups.c (getugroups): Use gid_t. * tests/test-getgroups.c (main): Likewise. * NEWS: Mention the signature change. * doc/posix-functions/getgroups.texi (getgroups): Mention the problem with signature. * doc/glibc-functions/setgroups.texi (setgroups): Mention that GETGROUPS_T is still useful for setgroups.

| | | | | | | | | | | | | | | | | | Avoid link failure on mingw, which lacks getgroups and anything else related to gid_t management (stat.st_gid is always 0). * lib/getgroups.c (getgroups): Provide ENOSYS stub for mingw. * lib/getugroups.c (getugroups): Likewise. * m4/getgroups.m4 (gl_FUNC_GETGROUPS): Check for missing function.
