L_DicomSendCFindResponse

#include "ltdic.h"

L_LTDIC_API L_INT L_DicomSendCFindResponse(hNet, nPresentationID, nMessageID, pszClass, nStatus, hDS)

Sends a C-FIND-RSP message to a peer member of a connection.

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_UINT16 nStatus

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

HDICOMDS hDS

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

Returns

Value	Meaning
DICOM_SUCCESS	The function was successful.
>0	An error occurred. Refer to Return Codes.

Comments

L_DicomSendCFindResponse is sent by the SCP in response to an L_DicomSendCFindRequest call placed by an SCU. This generates a call to RECEIVECFINDRESPONSECALLBACK on the SCU.
