file abi.h Arrow C Data Interface

The Arrow C Data interface defines a very small, stable set of C definitions which can be easily copied into any project's source code and vendored to be used for columnar data interchange in the Arrow format. For non-C/C++ languages and runtimes, it should be almost as easy to translate the C definitions into the corresponding C FFI declarations.

Applications and libraries can therefore work with Arrow memory without necessarily using the Arrow libraries or reinventing the wheel. Developers can choose between tight integration with the Arrow software project or minimal integration with the Arrow format only.
