NAME

initgroups − initialize group access list

SYNTAX

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

DESCRIPTION

The initgroups subroutine reads through the group file and sets up, using the setgroups() 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. 

RESTRICTIONS

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

RETURN VALUE

The initgroups returns −1 if it was not invoked by the superuser.
