   NAME
         setpgrp - set process group ID

   SYNOPSIS
         #include <sys/types.h>
         #include <unistd.h>

         pid_t setpgrp (void);

   DESCRIPTION
         If the calling process is not already a session leader, setpgrp sets
         the process group ID and session ID of the calling process to the
         process ID of the calling process, and releases the calling process's
         controlling terminal.

   SEE ALSO
         intro(2), exec(2), fork(2), getpid(2), kill(2), setsid(2), signal(2).

   DIAGNOSTICS
         setpgrp returns the value of the new process group ID.

   NOTES
         setpgrp will be phased out in favor of the setsid(2) function.
