LIBRARY¶
libzip (-lzip)SYNOPSIS¶
#include <zip.h>
typedef void (*zip_progress_callback)(zip_t *, double, void *);
void
zip_register_progress_callback_with_state
(zip_t
*archive, double
precision,
zip_progress_callback
callback, void
(*ud_free)(void *), void
*ud);
DESCRIPTION¶
Thezip_register_progress_callback_with_state
() function
registers a callback function callback for the zip
archive archive. The precision
argument is a double in the range from 0.00 to 1.0 that defines the smallest
change for which the callback should be called (to avoid too frequent calls).
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 progression state as a double, and the user-provided user-data ud as arguments. The progression state is a double in the range from 0.0 to 1.0. This can be used to provide progress indicators for user interfaces.
