SETGROUPS(2) BSD Programmer's Manual SETGROUPS(2)
setgroups - set group access list
#include <sys/types.h>
#include <unistd.h>
int
setgroups(int ngroups, const gid_t *gidset);
setgroups() sets the group access list of the current user process ac-
cording to the array gidset. The parameter ngroups indicates the number
of entries in the array and must be no more than {NGROUPS_MAX}.
Only the superuser may set new groups.
A 0 value is returned on success, -1 on error, with an error code stored
in errno.
The setgroups() call will fail if:
[EINVAL] The value of ngroups is greater than {NGROUPS_MAX}.
[EPERM] The caller is not the superuser.
[EFAULT] The address specified for gidset is outside the process ad-
dress space.
