Used for indicating the progress of a certain task.
The function pointer argument has to be supplied with a valid function of the given signature which will then be called on progress changes. An equivalent progress_t structure will be passed back as argument to the callback function on each progress change. The factor field of the supplied progress_t structure will then reflect the current progress as value between 0.0 and 1.0. You might want to use the custom field for data needed in your callback function.
