GETPGRP(2-POSIX)    RISC/os Reference Manual     GETPGRP(2-POSIX)



NAME
     getpgrp - get process group

SYNOPSIS
     #include <sys/types.h>

     pidt getpgrp()

DESCRIPTION
     getpgrp returns the process group ID of the calling process.

     Process groups are used for distribution of signals, and by
     terminals to arbitrate requests for their input; processes
     that have the same process group as the terminal are fore-
     ground processes.

     This call is thus used by programs such as csh(1) to create
     process groups in implementing job control.  The tcgetpgrp
     and tcsetpgrp calls are used to get/set the process group of
     the control terminal.

     tcsetpgrp(3).
