       The  function zip_source_read() reads up to len bytes of data from source at the current read offset into
       the buffer data.

       The zip source source has to be opened for reading by calling zip_source_open(3) first.

zip_source_read() was added in libzip 1.0.

       libzip (-lzip)

       Upon successful completion the number of bytes read is returned.  When zip_source_read() is called  after
       reaching  the  end  of  the  file, 0 is returned.  Otherwise, -1 is returned and the error information in
       source is set to indicate the error.
