.SH DESCRIPTION
|
||
|
|
.B Getgid
|
||
|
|
returns the real group ID of the current process,
|
||
|
|
.B getegid
|
||
|
|
the effective group ID.
|
||
|
|
.PP
|
||
|
|
The real group ID is specified at login time.
|
||
|
|
.PP
|
||
|
|
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 \fBgetgid\fP is most useful.
