pUserData

pointer to additional parameters

Comments

Call this function to set the DICOMDIR callbacks to be used. Currently, there is only one callback ( INSERTDICOMFILECALLBACK), but others may be added in future releases.

pUserData is Void pointer that you can use to pass one or more additional parameters that the callback function needs.

To use this feature, assign a value to a variable or create a structure that contains as many fields as you need. Then, in this parameter, pass the address of the variable or structure, casting it to L_VOID *.

The INSERTDICOMFILECALLBACK, which will receive the address in its own pUserData parameter, can cast it to a pointer of the appropriate data type to access your variable or structure.

If the additional parameters are not needed, you can pass NULL in this parameter.
