Parameter

Description

hNet

A DICOM Network handle.

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.

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.

pszClass

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

nStatus

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

hDS

Pointer to the data set that contains the information found as a result of the call to L_DicomSendCFindRequest.

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_DicomSendCFindResponse is called by the SCP.

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