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 at least 133 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:

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

	This function requires the following include files:

	cbslib_h, acnet_errors.h
