acnet_task_exists_c

	status.i4.v = acnet_task_exists_c(node.i4.v, task_name.i1a.r,
					  exists.i4.r [,task_id.i4.r])

	This routine will determine if an ACNET task exists.

	node		ACNET node (constants are in 'nodedefs')
	task_name	ACNET task name (up to PROCESS_NAME_LEN characters)
	exists		returned existence flag
			(TRUE -> process exists,
			 FALSE -> task does not exist)
	[task_id]	returned ACNET task ID
			(default is NULL)

	This function returns ACNET status values as follows:

	OK			success
	ACNET_NOCON		not connected to ACNET
	ACNET_xxx		error requesting task status

	This function requires the following include files:

	clib_h, nodedefs_h, acnet_errors_h

	Related functions:

	acnet_task_info_c, node_acnet_ping_c

	C/C++ usage:

	static const char	task_name[PROCESS_NAME_LEN+1] = "PA1028";
	int	status;
	int	node = CLX7;
	int	exists;
	int	task_id;

	status = acnet_task_exists_c(node,task_name,&exists,&task_id);
