L_DicomSendCFindResponse

#include "ltdic.h"

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

HDICOMNET hNet;	/* a DICOM Network handle */
L_UCHAR nPresentationID;	/* presentation ID */
L_UINT16 nMessageID;	/* message ID */
L_CHAR * pszClass;	/* class type */
L_UINT16 nStatus;	/* status of the request */
HDICOMDS hDS;	/* data set */

Sends a C-FIND-RSP message to a peer member of a connection. This function is available in the Medical Suite Toolkit.

Parameter	Description
hNet	A DICOM Network handle to the peer member of the connection.
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.

Returns

0	SUCCESS
>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.
