typedef void (*zip_cancel_callback)(zip_t *, double, void *);
zip_register_cancel_callback_with_state(zip_t *archive, zip_cancel_callback callback, void (*ud_free)(void *), void *ud);
This function can be used to cancel writing of a zip archive during zip_close(3).
zip_register_cancel_callback_with_state() function registers a callback function callback for the zip archive archive. The ud_free function is called during cleanup for deleting the userdata supplied in ud.
The callback function is called during zip_close(3) in regular intervals (after every zip archive entry that's completely written to disk, and while writing data for entries) with zip archive archive, the current progress state (see zip_register_progress_callback_with_state(3)) as a double, and the user-provided user-data ud as arguments. The progress state is a double in the range from 0.0 to 1.0.
The callback function should be fast, since it will be called often.
