NAME

setgrp − set/get group access

SYNOPSIS

setgrp(newgroups, oldgroups)
int ∗newgroups, ∗oldgroups;

DESCRIPTION

Setgrp sets the group access of the current user process according to the bit array pointed to by newgroups.  Each bit in the array which is set allows access to the correspondingly numbered group; each bit which is clear denies access.  The array has size NGRPS bits, defined in <sys/param.h>.  The old value of the groups mask is returned in the bit array referenced by oldgroups.  Either newgroups or oldgroups may be omitted by specifying 0. 

Only the super-user may set new groups.

BUGS

Group ID numbers are allowed to range only from 0 through 255. 

This call is provisional, and will exist in a slightly different form in 4.2bsd.
