status.i4.v = daq_retrieve_fe_activity_c(fe_node.i4.v, client_node.i4.v,
						 num_tasks.i4.r, tasks.sp.r)

	This routine will retrieve tasks referencing a front end
	node (single node or all nodes).

	fe_node		front end node to check
	client_node	node to search (Use a value of ALL_NODES if you
			want to retrieve all front end accesses.)
	num_tasks	returned number of matching tasks found
	tasks		returned matching task information
			(array of structures of type DPM_TASK_INFO_DATA)
			(Note: The memory for these structures is allocated
			 by this routine and should not be freed by the caller.)

	This function returns ACNET status values as follows:

	OK			success
	CLIB_BUGCHK		request/reply mismatch
	ACNET_UTIME		reply timed out
	ACNET_xxx		request failed

       This function requires the following include files:

	cbslib_h, acnet_errors_h
