INITGROUPS(3)                        BSD                         INITGROUPS(3)



NAME
     initgroups - initialize group access list

SYNOPSIS
     initgroups(name, basegid)
     char *name;
     int basegid;

DESCRIPTION
     initgroups reads through the group file and sets up, using the
     setgroups(2) call, the group access list for the user specified in name.
     The basegid is automatically included in the groups list.  Typically,
     this value is given as the group number from the password file.

FILES
     /etc/group

SEE ALSO
     setgroups(2)

DIAGNOSTICS
     initgroups returns -1 if it was not invoked by the super-user.

BUGS
     initgroups uses the routines based on getgrent(3).  If the invoking
     program uses any of these routines, the group structure will be
     overwritten in the call to initgroups.
