ATPRspCancel

Dequeue a call

#include <AppleTalk.h> AppleTalk Manager

OSErr ATPRspCancel(abRecord , async);

ATATPRecHandle abRecord; handle to an ATATPRec

Boolean async ; 0=await completion; 1=immediate return

returns Error Code; 0=no error

ATPRspCancel is part of the AppleTalk alternate interface. It is

recommended that you use the preferred call, PRelRspCB instead.

abRecord is a handle to an ATATPRec structure

async is a Boolean value. Use FALSE for normal ( synchronous) operation

or TRUE to enqueue the request and resume control immediately. See

Async I/O.

Returns: an operating system Error Code. It will be one of:

noErr (0) No error

cbNotFound (-1102) ATP Control Block not found

Notes: Given the handle to the ATATPRec of a previously made ATPSndRsp or

ATPResponse call, provided that the call has not already completed.

is successfully removed from the queue. If it returns cbNotFound, check

the abResult field of abRecord to verify that the ATPSndRsp or

ATPResponse call has completed and determine its outcome.
