zip_source_begin_write, zip_source_begin_write_cloning − prepare zip source for writing
zip_source_begin_write_cloning(zip_source_t *source, zip_uint64_t offset);
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.
Upon successful completion 0 is returned. Otherwise, −1 is returned and the error information in source is set to indicate the error.
