zip_get_file_comment —
get comment for file in zip (obsolete interface)
#include <zip.h>
const char *
  
  zip_get_file_comment(zip_t
    *archive, zip_uint64_t
    index, int *lenp,
    int flags);
The zip_get_file_comment() function is the obsolete
  version of
  zip_file_get_comment(3).
  The only differences are the types of the lenp and
  flags arguments.
zip_get_file_comment() was added in libzip 0.7. In
  libzip 0.10 the type of index was changed from
  int to zip_uint64_t. It was
  deprecated in libzip 0.11, use zip_file_get_comment()
  instead.
