# Multithreaded Embedding

You can also browse this source code online and clone the wasmtime
repository to run the example locally:

* [Rust](https://github.com/bytecodealliance/wasmtime/blob/main/examples/threads.rs)
* [C](https://github.com/bytecodealliance/wasmtime/blob/main/examples/threads.c)
* [C++](https://github.com/bytecodealliance/wasmtime/blob/main/examples/threads.cc)

This example demonstrates using Wasmtime in multithreaded runtimes.
