zip_register_cancel_callback_with_state(3) Library Functions Manual
NAME
zip_register_cancel_callback_with_state - allow cancelling during zip_close
LIBRARY
libzip (-lzip)
SYNOPSIS
#include <zip.h>
typedef int (*zip_cancel_callback)(zip_t *, void *);
void
zip_register_cancel_callback_with_state(zip_t *archive,
zip_cancel_callback callback, void (*ud_free)(void *), void *ud);
DESCRIPTION
This function can be used to cancel writing of a zip archive during
zip_close(3).
The 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 and the user-provided
user-data ud as arguments. When the callback function returns a non-zero
value, writing is cancelled and zip_close(3) returns an error.
The callback function should be fast, since it will be called often.
