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, 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.
