# Arena allocator

A very simple C++ arena allocator using POSIX mmap.

It is unfit for commercial usage and should be only used for

educational purposes.

## Install

```bash

sudo make install

```

## Test

To run a test program, run

```bash

make test

```

## Example

```c++

#include 

int main (int argc, char ** argv)

{

    arena::allocator Lifetime = arena::allocator::create(400);

    int * Buf_1 = Lifetime.allocate(120);

    int * Buf_2 = Lifetime.allocate(80);

    int * Buf_3 = Lifetime.allocate(200);

    // Further allocation will yield null as arena's memory is over

    // Arena's memory is deallocated when it goes out of scope

}

```
