status.i4.v = pid_to_process_name_c(pid.i4.v, process_name.i1a.r

	This routine returns the process name corresponding to a pid.

	pid		pid of interest
	process_name	returned process name
			(allow PID_INFO_NAME_LEN + 1 characters)
	[node]		node of interest
			(default is LOCAL)

	This function returns ACNET status values as follows:

	OK			success
	CLIB_NO_SUCH		pid doesn't exist
	CLIB_BUGCHK		unexpected error processing pid information

	This function requires the following include files:

	cbslib_h, acnet_errors_h

	Related functions:

	process_name_to_pid_c, process_info_by_pid_c, process_information,
	find_processes_c, pid_process_exists_c

	C/C++ usage:

	char	process_name[PID_INFO_NAME_LEN+1];
	int	status;
	int	pid;
	int	node = LOCAL;

	status = pid_to_process_name_c(pid,process_name,node);
