#include "ltdic.h"

L_VOID pEXT_CALLBACK Your Function(hNet, nError, nType, nBytes, UserData)

Notifies a connection that data was sent. This function is available in the PACS Imaging.

Parameters

A DICOM Network handle.

L_INT nError

Error code. Refer to Return Codes.

The type of data that was sent. Possible values are:

L_UINT32 nBytes

Number of bytes of data actually sent.

L_VOID * UserData

Void pointer that you can use to access a variable or structure containing data that your callback function needs. This gives you a way to receive data indirectly from the function that uses this callback function.

Keep in mind that this is a void pointer, which must be cast to the appropriate data type within your callback function.

Returns

None.

Comments

When one of the L_DicomSendXXX functions is called, the message is not sent immediately. It is placed in a Network queue and sent later. When the data is actually sent, this callback function is called to let the calling AE know that the data has been sent.

To use this callback function, SENDCALLBACK must be set using L_DicomSetCallback.
