#include "ltdic.h"

L_INT EXT_FUNCTION L_DicomSendCEchoRequest(hNet, nPresentationID, nMessageID, pszClass)

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

Sends a C-ECHO-REQ 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.

Returns

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

Comments

Calling this function generates a call to RECEIVECECHOREQUESTCALLBACK on the SCP. The SCP should respond by calling L_DicomSendCEchoResponse which will generate a call to RECEIVECECHORESPONSECALLBACK.
