libzipis a library for reading, creating, and modifying zip archives.
The main design criteria for
- Do not create corrupt files, even in case of errors.
- Do not delete data.
- Be efficient.
For this reason, when modifying zip archives,
libzip writes to a temporary file and replaces the
original zip archive atomically.
Below there are two sections listing functions: one for how to read from zip archives and one for how to create/modify them.
Names of files inside archives are by default expected in UTF-8
encoding. Other encodings can be requested by using the flags
For details see the relevant man pages.
libzipdoes not automatically convert them, even on Windows. It is the responsibility of the programmer to ensure that all directory separators are passed as forward slashes to
libzipare independent of each other and can be used by parallel-running threads without locking. If you want to use an archive from multiple threads, you have to synchronize access to it yourself. If you use an archive as a source for zip_file_add(3) or zip_file_replace(3), access to the target archive must be synchronized with access to the source archive as well.
