ffsys
ffsys is a cross-platform interface that wraps the system functions of different OS to provide you with a unified userspace API. In other words, you write the single chunk of code that is translated to system-specific code during compilation, and that's how it works on different OS.
Supported OS:
- Linux and Android
- FreeBSD
- macOS
- Windows
ffsys advantages:
- No external dependencies - built upon
libcandkernel32.dll - No overhead - everything is inlined during the compiler's optimization
- Header-only - it's convenient to just
#includethe necessary files directly into your C/C++ source file - Clean and straightforward code that you can copy-paste anywhere

How to use
ffsys code is split between 2 repos:
- ffbase library that provides base types & algorithms for C. It is also header-only.
- This repo contains system function wrappers. It uses
ffbase, e.g. for string manipulation and Unicode conversion functions.
Step 1. In your terminal window:
cd YOUR_PROJECT
git clone https://github.com/stsaz/ffsys
git clone https://github.com/stsaz/ffbase
Step 2. In your Makefile:
FFSYS := YOUR_PROJECT/ffsys
FFBASE := YOUR_PROJECT/ffbase
CFLAGS += -I$(FFSYS) -I$(FFBASE)
Optional preprocessor flags:
| Flag | Description |
|---|---|
FF_MUSL | UNIX: Compile for musl C library |
Step 3. In your C source files:
#include <ffsys/...>
Test
git clone https://github.com/stsaz/ffbase
git clone https://github.com/stsaz/ffsys
cd ffsys/test
make -j8
./ffsystest all
on FreeBSD:
gmake -j8
on Linux for Windows:
make -j8 OS=windows COMPILER=gcc CROSS_PREFIX=x86_64-w64-mingw32-
