#include "ltdic.h"

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

Notifies a connection that a C-FIND-REQ command was received. This function is available in the PACS Imaging.

Parameters

HDICOMNET hNet

A DICOM Network handle.

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_UINT16 nPriority

The priority level of the message. The Service Class Provider may or may not support priority. Therefore, setting this parameter may or may not have any effect. Possible values are:

Value Meaning
COMMAND_PRIORITY_LOW [0x0002] Low priority message.
COMMAND_PRIORITY_MEDIUM [0x0000] Medium priority message.
COMMAND_PRIORITY_HIGH [0x0001] High priority message.

HDICOMDS hDS

Pointer to the data set to be found.

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
