Routines / Canceling Pending ATP Functions

ATPKillAllGetReq

The ATPKillAllGetReq function cancels all pending calls to the PGetRequest function for a specific socket.

FUNCTION ATPKillAllGetReq (thePBPtr: ATPPBPtr; 
                           async: Boolean): OSErr;

thePBPtr

A pointer to an ATP parameter block.

async

A Boolean that indicates whether the function should be executed asynchronously or synchronously. Specify TRUE for asynchronous execution.

-->	ioCompletion	ProcPtr	A pointer to the completion routine.
<--	ioResult	OSErr	The function result.
-->	csCode	Integer	Always killAllGetReq for this function.
-->	atpSocket	Byte	The socket number whose pending PGetRequest functions are to be canceled.

Field Description

atpSocket

The socket whose pending PGetRequest functions are to
be canceled.

DESCRIPTION

The ATPKillAllGetReq function cancels all pending PGetRequest functions issued on a specific socket without closing the socket. For each function executed asynchro-
nously, ATPKillAllGetReq also calls the completion routine with the value reqAborted (-1105) in the D0 register. You should call the ATPKillAllGetReq function before closing a socket.

ASSEMBLY-LANGUAGE INFORMATION

To execute the ATPKillAllGetReq function from assembly language, call the _Control trap macro with a value of killAllGetReq in the csCode field of the parameter block. To execute this function from assembly language, you must also
specify the .ATP driver reference number.

RESULT CODES

noErr	0	No error
cbNotFound	-1102	Control block not found; no pending asynchronous calls
