libffi

Libffi is a library that provides a portable interface that allows calling code written in one language to call code written in another language. It is most commonly used for interoperability between high-level languages and low-level languages.

Libffi is maintained by the open source community. The original code was written by Anthony Green and maintained by the Free Software Foundation.

Libffi supports multiple programming languages including C, C++, Rust, Java, Python, and many more. It can be used to bridge the gap between these different languages.

Yes, one of the key features of libffi is its platform independence. It provides a consistent interface regardless of the underlying operating system or architecture.

Libffi can be used by including its header files in the project and linking against its library. This allows for seamless integration with other codebases that might be using different programming languages.

There might be some performance overhead when using libffi due to the abstraction layer it provides. However, this overhead is usually minimal compared to the benefits of language interoperability it offers.

Yes, libffi supports calling functions with variable arguments using its API. This feature is particularly useful for handling functions with varying argument lists.

Yes, libffi is thread-safe and can be used in multi-threaded applications without any issues. It ensures that concurrent calls to its API do not cause unexpected behavior.

Libffi is distributed under a permissive license, usually the MIT license or similar licenses that allow for free use and distribution of the library in both open source and commercial projects.

Yes, there are other libraries that provide similar functionality to libffi, such as Foreign Function Interface (FFI) libraries specific to certain programming languages. However, libffi is widely used due to its portability and support for multiple languages.
