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

     contains 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.
