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


a DICOM Network handle

L_INT nError;

L_UCHAR nType;

type of message/data sent

L_UINT32 nBytes;

number of bytes of data sent

L_VOID * UserData;

pointer to additional data

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

Parameter Description
hNet A DICOM Network handle.
nError Error code. Refer to Return Codes.
nType The type of data that was sent. Possible values are:
  Value Meaning
  PDU_UNKNOWN [0x00] Unknown data sent.
  PDU_ASSOCIATE_REQUEST [0x01] Associate Request message sent
  PDU_ASSOCIATE_ACCEPT [0x02] Associate Accept message sent
  PDU_ASSOCIATE_REJECT [0x03] Associate Reject message sent
  PDU_DATA_TRANSFER [0x04] Data transfer made.
  PDU_RELEASE_REQUEST [0x05] Release Request message sent
  PDU_RELEASE_RESPONSE [0x06] Release Response message sent
  PDU_ABORT [0x07] Abort message sent.
nBytes Number of bytes of data actually sent.
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.




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.
