#include "ltdic.h"

L_LTDIC_API L_INT L_DicomSendCEchoResponse(hNet, nPresentationID, nMessageID, pszClass, nStatus)

HDICOMNET hNet;	/* a DICOM Network handle */
L_UCHAR nPresentationID;	/* presentation ID */
L_UINT16 nMessageID;	/* message ID */
L_TCHAR * pszClass;	/* class type */
L_UINT16 nStatus;	/* status */

Sends a C-ECHO-RSP message to a peer member of a connection. This function is available in the PACS Imaging 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.

Returns

0	SUCCESS
>0	An error occurred. Refer to Return Codes.

Comments

L_DicomSendCEchoResponse is sent by the SCP in response to an L_DicomSendCEchoRequest call placed by an SCU. This generates a call to RECEIVECECHORESPONSECALLBACK on the SCU.
