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 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.
libzip(3),

zip_register_progress_callback_with_state
()
was added in libzip 1.3.0.
