getgrouplist(3) is not a POSIX function; it's from 4.4BSD (and thus
NetBSD/FreeBSD/OpenBSD have it):
int getgrouplist(const char *name, gid_t basegid,
gid_t *groups, int *ngroups);
I have no idea if glibc has it or has the same API as 4.4BSD (it's likely).
getgroups(2) is probably the POSIX function you're referring to:
int getgroups(int gidsetsize, gid_t grouplist);
