Show in webframe

#include "ltdic.h"

virtual L_VOID LDicomNet::OnAccept(nError)

L_INT nError;

/* error code */

Notifies a listening connection (SCP) that it can accept pending connection requests. This function is available in the PACS Imaging Toolkit.

Parameter	Description
nError	Error code. Refer to Return Codes.

Returns

None.

Comments

A call to this function is generated on an SCP when an SCU calls LDicomNet::Connect.

To accept a connection request, call LDicomNet::Accept.

You should always accept a connection request. Once the connection is made you can check the client and close the connection if you do not wish to maintain it. Since the connection requests are queued, if you do not accept a connection, it remains in the queue. When the next request is received, it is placed in the queue behind the first request. Calling LDicomNet::Accept at this point will connect the first request, not the second, since the first request is still in the queue.
