#illusory0x0/posix

#Description

a simple posix API FFI library (WIP).

Provide posix standard in unistd.h most of the functions, the same category of functions only at series of functions and functions to support file descriptor operations, as far as possible to avoid the use of CString to operate the file, such as only fchownat and fchown no chown, first open the file to obtain the file descriptor and then operate the file.

Currently waiting for official build system and FFI toolchain support. FFI Tools like rust bindgen

In /src/example directory provides a number of useful examples.

Currently supported interfaces can be viewed at posix.mbti

#Usage

Reduce the overhead of static library function calls by enable lto when release.

#Name convention

FFI namespace moonbit_posix_
