# Fastprocess
A fast subprocess library

> [!NOTE]
> This library is no longer maintained.
>
> Modern versions of subprocess are very close to as fast as this library, so just use that :)

## Usage
Spawning a process with fastprocess is very easy
```
In [1]: from fastprocess import FastProcess

In [2]: pid = FastProcess(['echo', 'hello', 'world'])

hello world
In [3]: pid.wait()
Out[3]: 0

```
You can redirect io using the stdin, stdout, and stderr options
```
In [4]: null = open('/dev/null', 'w')

In [5]: pid = FastProcess(['yes'], stdout=null)

In [6]: pid.terminate()
```

## FastProcess methods
terminate():  
Sends SIGTERM to the process

kill(sig):  
Sends signal 'sig' to the process

wait():  
Waits for the process to exit then returns the exit code

## Performance
Here are the results of running ./benchmark/bench
