Shmex is a library providing Elixir bindings for shared memory and native
functions to manipulate it in NIFs.

Documentation is available at [HexDocs](https://hexdocs.pm/shmex)

The source code is available at [GitHub](https://github.com/membraneframework/shmex)

## Installation

Add the following line to your `deps` in `mix.exs`. Run `mix deps.get`.

```elixir
	{:shmex, "~> 0.5.1"}
```

All native stuff is exported in `:lib` and `:shmex` [Bundlex](https://hex.pm/packages/bundlex) dependencies.
To import, add the following line to your nif specification in `bundlex.exs`
```elixir
deps: [shmex: :lib]
```
and another one in your native header file
```c
#import <shmex/lib.h>
```

## Testing

To execute tests run `mix test`. These test tags are excluded by default:
- `shm_tmpfs` - tests that require access to information about shared memory segments present in the OS via tmpfs, not supported e.g. by Mac OS
- `shm_resizable` - tests for functions that involve resizing existing shared memory segments, not supported e.g. by Mac OS
