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

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

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_UINT16 nStatus

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