wasix | POSIX compatibility layer for WASI builds

wasix is a C library typically used in Binary Executable Format applications. wasix has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

This library provides stubs for POSIX compatibility when compiling sources using the WASI SDK. The WASI SDK and the accomanying wasi-libc do provide some POSIX functionality, but many functions that are not currently supported or do not make sense in the context of WASM are missing. This can make it difficult to compile sources to WASI that expect POSIX compatibility. The library in this project aims to fill the gaps between POSIX and WASI. In many cases, the implementation of functions will simply return an error code, but it will allow many 3rd party sources to compile using WASI and access any functionality that doesn't require the stubbed out functions. Some functions (e.g., getpid, getuid, getgid) are implemented to return a static value given at compile time or an environment variable specified at runtime. This allows you to more closely emulate some POSIX functions in your environment as needed.
