    Koffi is a fast and easy-to-use C FFI module for Node.js, featuring:

    • Low-overhead and fast performance (see benchmarks)
    • Support for primitive and aggregate data types (structs and fixed-size arrays), both by reference (pointer) and by value
    • Javascript functions can be used as C callbacks (since 1.2.0)
    • Well-tested code base for popular OS/architecture combinations

    The following combinations of OS and architectures are officially supported and tested at the moment:

    ISA / OS Windows Linux macOS FreeBSD OpenBSD
    x86 (IA32) 1 Yes Yes ⬜️ N/A Yes Yes
    x86_64 (AMD64) Yes Yes Yes Yes Yes

    1. The following call conventions are supported: cdecl, stdcall, MS fastcall, thiscall.

    2. The prebuilt binary uses the hard float ABI and expects a VFP coprocessor. Build from source to use Koffi with a different ABI (softfp, soft).

    3. The prebuilt binary uses the LP64D (double-precision float) ABI. The LP64 ABI is supported in theory if you build Koffi from source (untested), the LP64F ABI is not supported.
