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

DIOCM_SUCCESS

The function was successful.

>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.
