NAME

       gong - evaluate process performance

SYNOPSIS

       gong [-f] [-a] process-id

DESCRIPTION

       Gong is used to evaluate the performance of a process that is in execution.

       The  process-id	is  the process number of the process whose performance is to be evaluated.  The evaluation is performed by a set of three
       ``panelist'' routines, each of which analyzes one aspect (time, space, and tonality) of the performance of the process.	If  any  of  these
       routines is not amused by the performance, the process being analyzed is sent the gong(2) signal.  In addition, the process-id of the eval-
       uated process is written on the standard gong, for possible future corrective action.  (It is suggested that the standard gong be an  audi-
       ble alarm for proper effect.)  It is expected that after being gong(2)ed, the process will promptly commit suicide.

       The  -f	keyletter  argument  indicates	that  gong  is	to  invoke flog(1) with the unmerciful argument if the process does not respond to
       gong(2)ing.  In the absence of this argument, the process is continuously gong(2)ed, which may lead to the process becoming a deaf zombie.

       The -a keyletter argument indicates that if all three of the panelist routines gong(2)  a  process,  the  process  should  be  unmercifully
       flog(1)ged whether or not the -f keyletter is supplied.

FILES

       /dev/ding.dong is the standard gong.

BUGS

       If the named process does not exist, it is possible that gong will attempt an evaluation of itself, which may lead to a condition known	as
       compounded double ringing (see echo(1)).  Therefore, it is recommended that gong be used with extreme care.

NAME

       getpid(), getpgid(), getpgrp(), getpgrp2(), getppid() - get process, process group and parent process ID.

SYNOPSIS

DESCRIPTION

       These functions return process, process group and parent process IDs, as follows:

	      Process group ID of the specified process.
				  If pid is zero, the call applies to the calling process.  Same result as

	      Process group ID of the calling process.

	      Process group ID of the specified process.
				  If pid is zero, the call applies to the calling process.  Same result as

	      Process ID of the calling process.

	      Parent process ID of the calling process.
				  If the parent process is the initialization process (known as the call returns 1.

   Security Restrictions
       The  system  call is subject to compartmental restrictions.  See compartments(5) for more information about compartmentalization on systems
       that support that feature.

       Compartmental restrictions can be overridden if the process possesses the privilege (PRIV_COMMALLOWED).	Processes owned by  the  superuser
       may  not  have  this privilege.	Processes owned by any user may have this privilege, depending on system configuration.  See privileges(5)
       for more information about privileged access on systems that support fine-grained privileges.

RETURN VALUE

       The functions return the following values:

	      Successful completion.
		     n is a nonnegative process ID, as described above.
	      Failure:
		     and only.	is set to indicate the error.

ERRORS

       If or fails, is set to one of the following values:

	      [EPERM]	     The current process and pid are not in the same session (see setsid(2)).

	      [ESRCH]	     No process can be found corresponding to that specified by pid.
