pid_process_exists_c

	status.i4.v = pid_process_exists_c(pid.i4.v [,node.i4.v])

	This routine determines if a given process ID points to an
	existing process.

	pid		pid of interest
	[node]		node of interest
			(default is LOCAL)

	This function returns ACNET status values as follows:

	TRUE			pid points to a an existing process
	FALSE			pid does not point to an existing process
	otherwise		other ACNET format error code

	This function requires the following include files:

	cnsparam_h, cbslib_h, acnet_errors_h

	process_information, find_processes_c

	C/C++ usage:

	int	status;
	int	pid = PID;
	int	node = LOCAL;

	status = pid_process_exists_c(pid,node);
