LIBRARY

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.
