Debian                                          December 18, 2017                      ZIP_SOURCE_BEGIN_WRITE(3)

       The  functions  zip_source_begin_write() and zip_source_begin_write_cloning() prepare source for writing.
       Usually this involves creating temporary files or allocating buffers.

       zip_source_begin_write_cloning() preserves the first offset bytes of the original  file.   This  is  done
       efficiently, and writes to source won't overwrite the original data until zip_commit_write() is called.

zip_source_begin_write() was added in libzip 1.0.

       zip_source_begin_write_cloning() was added in libzip 1.4.0.

       Upon  successful completion 0 is returned.  Otherwise, -1 is returned and the error information in source
       is set to indicate the error.
