acl_cancel_requests_c

	status.i4.v = acl_cancel_requests_c(compiled_code.g.v, options.u4.v,
					    error_string.i1a.r)

	This routine cancels requests for Accelerator Command Language
	(ACL) code.  This code must have been compiled by an earlier
	call to acl_compile_c.

	compiled_code	compiled_code
			(This should have been returned by an earlier
			 call to acl_compile_c.)
	options		options (not presently used)
			(ACL_OPT_NONE -> no options selected)
	error_string	returned error string
			(Allow ACL_ERROR_STRING_LEN + 1 characters.)
			(A value of NULL can be passed for this argument
			 if this information is not needed.)

	This function returns ACNET status values as follows:

	OK			success
	CLIB_INVARG		not a valid block of compiled code
	CLIB_NOTYET		invalid command encountered

	This function requires the following include files:

	ul_acl_h:acl_h, acnet_errors_h
