ZIP_REGISTER_PROGRESS... BSD Library Functions Manual ZIP_REGISTER_PROGRESS...
NAME
zip_register_progress_callback_with_state — provide updates during
zip_close
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
The zip_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 ar-
guments. 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.
