This group list is then setup for the current process using
setgroups(2).
The
Fa basegid
is automatically included in the groups list.
Typically this value is given as
the group number from the password file.
RETURN VALUES
Rv -std initgroups
ERRORS
The
initgroups ();
function may fail and set
errno
for any of the errors specified for the library function

The
getgrouplist ();
function called by

If the invoking program uses any of these routines,
the group structure will
be overwritten in the call to
initgroups (.);
