# libc_alloc
[](https://crates.io/crates/libc_alloc)
[](https://docs.rs/libc_alloc)
A simple global allocator for Rust which hooks into `libc`.
Useful when linking `no_std` + `alloc` code into existing embedded C code.
On Unix-like OSs, use `posix_memalign` for allocations, `realloc` for reallocations, and `free` for deallocations.
On Windows, use native [`_aligned_malloc`](https://docs.microsoft.com/en-us/cpp/c-runtime-library/reference/aligned-malloc) for allocations, [`_aligned_realloc`](https://docs.microsoft.com/en-us/cpp/c-runtime-library/reference/aligned-realloc) for reallocations, and [`_aligned_free`](https://docs.microsoft.com/en-us/cpp/c-runtime-library/reference/aligned-free) for deallocations.
## Example
```rust
use libc_alloc::LibcAlloc;
#[global_allocator]
static ALLOCATOR: LibcAlloc = LibcAlloc;
```
## Project Status
Given how dead-simple this crate is, I doubt it will need to be updated very often.
