ATPAddRsp

Send one additional response packet

#include <AppleTalk.h> AppleTalk Manager

ATATPRecHandle abRecord; handle to an ATATPRec

returns Error Code; 0=no error

ATPAddRsp is part of the AppleTalk alternate interface. It is recommended

that you use the preferred call, PAddResponse instead.

ATPAddRsp sends one additional response packet to another socket.

abRecord is a handle to an ATATPRec structure. The relevant fields are as

follows:

Out-InName Type Size Offset Description

¨ abOpcode ABCallType 1 0 Always tATPAddRsp

¨ abResult short 2 2 Result code

Æ abUserReference long 4 4 For your use

Æ atpSocket short 2 0 Responding socket number

Æ atpAddress AddrBlock 4 2 Destination socket address

Æ atpReqCount short 2 6 Buffer size in bytes

Æ atpDataPtr Ptr 4 8 Pointer to buffer

Æ atpTransID short 2 24 Transaction ID

Æ atpUserData long 4 28 User bytes

¨ atpEOM Boolean 2 34 End-of-message flag

Æ atpNumRsp char 1 42 Sequence number

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

noErr (0) No error

badATPSkt (-1099) Bad ATP-responding socket

badBuffNum (-1100) Bad response buffer number specified

noSendResp (-1103) ATPAddRsp issued before ATPSndRsp

noDataArea (-1104) Too many outstanding ATP calls

Notes: ATPAddRsp sends one additonal packet to a socket that has already been

sent the initial part of a response via ATPSndRsp. ATPSocket contains the

socket number from which the response should be sent and atpAddress

contains the internet address of the socket to which the response should be

sent. ATPTransID must contain the transaction ID. ATPDataPtr and

atpReqCount specify the location and size of a buffer that contains the

information to send. ATPNumRsp is the sequence number of the response.

ATPEOM is TRUE if this response datagram is the final packet in a

transaction composed of a group of packets. ATPUserData contains the user

bytes to be sent in this response datagram's ATP header.

No BDS is needed with ATPAddRsp because all pertinent information is

passed within the record.
