<H2>DESCRIPTION</H2><PRE>
|
||||
<STRONG>Getgid</STRONG> returns the real group ID of the current process, <STRONG>getegid</STRONG> the
|
||||
effective group ID.
|
||||
|
||||
The real group ID is specified at login time.
|
||||
|
||||
The effective group ID is more transient, and determines additional
|
||||
access permission during execution of a ``set-group-ID'' process, and it
|
||||
is for such processes that <STRONG>getgid</STRONG> is most useful.
