RECEIVENGETRESPONSECALLBACK

#include "ltdic.h"

L_VOID pEXT_CALLBACK Your Function(hNet, nPresentationID, nMessageID, pszClass, pszInstance, nStatus, hDS, pUserData)

Notifies a connection that an N-GET-RSP command was received. This function is available in the Medical Imaging SuitePACS Imaging.

Parameters

HDICOMNET hNet

A DICOM Network handle to the peer member of the connection.

L_UCHAR nPresentationID

Presentation ID. The presentation ID provides information about both the class type of the data and the transfer syntax to use when transferring the data.

L_UINT16 nMessageID

Message ID. Each message sent by a member of a connection should have a unique ID. Since a member of a connection may send several messages, this ID allows that member to identify when a specific request has been completed.

L_TCHAR * pszClass

Class affected by the request. This will be an SOP Class or an SOP MetaClass.

L_TCHAR * pszInstance

The instance of the class. A server may, for example, have three instances of the Nuclear Medicine Class. This value identifies the data with a specific instance.

L_UINT16 nStatus

The status of the original request. For a list of possible values, refer to Status Constants.

HDICOMDS hDS

Data set that contains the retrieved elements.

L_VOID * pUserData

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

A call to this function is generated on an SCU when L_DicomSendNGetResponse is called by an SCP.

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