initgroups(3)                                       initgroups(3)



NAME
     initgroups - initializes 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.

STATUS MESSAGES AND VALUES
     The initgroups command returns -1 if it was not invoked by
     the superuser.

LIMITATIONS
     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.

FILES
     /etc/group
          File containing group information
     /etc/passwd
          File containing user information
