Debian                                         September 11, 2024                                   ZIP_FREAD(3)

       The  zip_fread()  function  reads  up to nbytes bytes from file into buf from the current position in the
       file (see zip_fseek(3)).  After reading, the current position is updated by the number of bytes read.

zip_fread()  was  added  in  libzip  0.6.   In  libzip  0.10  the return type was changed from ssize_t to
       zip_int64_t.  In libzip 0.10 the type of nbytes was changed from size_t to zip_uint64_t.

       zip_fread — read from file

       If successful, the number of bytes actually read is returned.  When zip_fread() is called after  reaching
       the end of the file, 0 is returned.  In case of error, -1 is returned.
