Arguments for callback function

A quick question, I noticed that in the example code given for
CFNetwork specifically:
void myWriteCallBack(CFWriteStreamRef stream, CFStreamEventType
event, void *myPtr)
There is a third argument myPtr. I wonder if this is used to pass
information about the stream to the callback function. If this is so,
how can I use it to pass a structure containing statistics about the
stream? Currently I'm declaring the structure global to be able to
access the information.
Thanks!
