Function Documentation

IDL_VPTR gs_cancel	(	int	argc,
		IDL_VPTR *	argv_idl
	)

The implementation of the gs_cancel() call. This cancels a previously submitted non-blocking request.

This is part of the IDL Client for GridSolve. GridRPC cancel call

Parameters:

	argc	-- the number of arguments
	argv_idl	-- the array of IDL arguments passed in this should contain one argument: the request ID of the job to cancel.

Returns:: an IDL variable containing the GridRPC exit status of the call. See the GridRPC documentation for details.

  req_id = IDL_LongScalar(argv_idl[0]);
