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 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.
