Parameter  | 
Description  | 
hNet  | 
A DICOM Network handle.  | 
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.  | 
pUserData  | 
Void pointer that you can use to access a variable or structure containing data that your callback function needs. This gives you a way to receive data indirectly from the function that uses this callback function.  | 
  | 
Keep in mind that this is a void pointer, which must be cast to the appropriate data type within your callback function.  | 
None.
A call to this function is generated on a peer member of a connection when L_DicomSendCEchoRequest is called.
To use this callback function, RECEIVECECHOREQUESTCALLBACK must be set using L_DicomSetCallback.
