INITGROUPS(3)	       FreeBSD Library Functions Manual		 INITGROUPS(3)

NAME
     initgroups	-- initialize group access list

LIBRARY
     Standard C	Library	(libc, -lc)

SYNOPSIS
     #include <unistd.h>

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

DESCRIPTION
     The initgroups() function uses the	getgrouplist(3)	function to calculate
     the group access list for the user	specified in name.  This group list is
     then setup	for the	current	process	using setgroups(2).  The basegid is
     automatically included in the groups list.	 Typically this	value is given
     as	the group number from the password file.

RETURN VALUES
     The initgroups() function returns the value 0 if successful; otherwise
     the value -1 is returned and the global variable errno is set to indicate
     the error.

ERRORS
     The initgroups() function may fail	and set	errno for any of the errors
     specified for the library function	setgroups(2).

SEE ALSO
     setgroups(2), getgrouplist(3)

HISTORY
     The initgroups() function appeared	in 4.2BSD.

BUGS
     The getgrouplist()	function called	by initgroups()	uses the routines
     based on getgrent(3).  If the invoking program uses any of	these rou-
     tines, the	group structure	will be	overwritten in the call	to
     initgroups().
