SETGROUPS(2)	    UNIX Programmer's Manual	     SETGROUPS(2)


NAME
     setgroups - set group access list

SYNOPSIS
     #include <sys/param.h>

     setgroups(ngroups, gidset)
     int ngroups, *gidset;

DESCRIPTION
     Setgroups sets the group access list of the current user
     process according to the array gidset.  The parameter
     ngroups indicates the number of entries in the array and
     must be no more than NGROUPS, as defined in <sys/param.h>.

     Only the super-user may set new groups.

RETURN VALUE
     A 0 value is returned on success, -1 on error, with a error
     code stored in errno.

ERRORS
     The setgroups call will fail if:

     [EPERM]	    The caller is not the super-user.

     [EFAULT]	    The address specified for gidset is outside
		    the process address space.

SEE ALSO
     getgroups(2), initgroups(3X)

BUGS
     The gidset array should be of type gid_t, but remains
     integer for compatibility with earlier systems.
