  actionReply | a pointer to the action reply dataset returned by the SCP is passed back in this parameter if the method returns with success status. Content is undefined otherwise. May return NULL if the SCP has not returned an attribute list. If a DICOM dataset is returned, it must be deleted by the caller.

Returns
  DIMSE_NORMAL if successful (e.g. no protocol failure), an error code otherwise.

## ◆ createRQ()

OFCondition DVPSPrintMessageHandler::createRQ | ( | const char * | sopclassUID,

Any event report requests incoming before the expected response message are handled.

Parameters

Parameters

  sopclassUID | the requested SOP class UID, must be one of the supported print classes.
  sopinstanceUID | the requested SOP instance UID
