Callback function

[MarcoMB]

I can't find a good definition and explanation about callback functions in Win32... can someone explain me what are callback functions and how they work and receive parameters?

A callback function is a pointer to a function. Look at qsort() for an example of using a function pointer.

thanks for reply but i don't understand if the callback function is called directly by operating system and if it must be a win api function or if i can create a user-defined callback function and i decide to call it calling the function that has its address as an argument

It can be a user defined function.
