L_VOID * UserData

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.

Comments

A call to this function is generated on an SCU when an SCP calls L_DicomAccept. It is generated whether the connection attempt is successful. It is also generated when a connection attempt has timed out.

To use this callback function, CONNECTCALLBACK must be set using L_DicomSetCallback.

A DICOM Association must be established between an SCU and an SCP before any DICOM messages or data can be transmitted between them. For more information on creating a DICOM Association, refer to Creating a DICOM Associate Connection.
