POSIX::1003::User - POSIX handling user and groups
POSIX::1003::User is a POSIX::1003::Module
User and group management is provided via many functions, which are not portable either in implementation or in availability. See also http://www.cs.berkeley.edu/~daw/papers/setuid-usenix02.pdf
The implementation of setuid() differs per platform. seteuid() is more consistent and widely available. setresuid() is the most powerful, but not everywhere. Functions which are not implemented will return error ENOSYS.
# see also the set*uid examples above my @mygroups = getgroups(); @mygroups or die $!; setgroups(1,2,3) or die $!;
The same use and limitations as the uid functions.
Returns a list of group-ids, which may (or may not) contain the effective group-id.
