Description

Summary

Add a C API crate that wraps wee_alloc and provides posix malloc and free.

Motivation

C and C++ projects targeting wasm could benefit from wee_alloc too, and more users = more bug reports and reliability work and all that good stuff.

Details

  • New crate at the top level of the repo, depending on wee_alloc

  • Wraps a wee_alloc global allocator and exposes malloc and free (and I think realloc is part of the posix spec too?)

Contributor guide

Research direction
Create a new crate at the top level that wraps wee alloc's global allocator and exposes malloc, free, and realloc. Use #[no mangle] and extern "C" to export functions. Ensure compatibility with POSIX.
