GETGID(II) 5/15/74 GETGID(II)
NAME
getgid - get group identifications
SYNOPSIS
(getgid = 47.; not in assembler)
sys getgid
getgid( )
DESCRIPTION
Getgid returns a word (in r0), the low byte of which con-
tains the real group ID of the current process. The high
byte contains the effective group ID of the current process.
The real group ID identifies the group of the person who is
logged in, in contradistinction to the effective group ID,
which determines his access permission at the moment. It is
thus useful to programs which operate using the ``set group
ID'' mode, to find out who invoked them.
