# Simple Thread Pool for POSIX pthread

This is a very simple implementation of a ThreadPool that uses POSIX threads. It's written to be simple, not versatile.

### License

MIT. In other words, you're free to do with this code whatever you want.

### Usage

There is an example on how to use the code in the directory `examples`. 

Other than that, all you have to do is:

 * Include the file `ThreadPool_pthread.h`
 * Add the sources in the directory `src` to your sources
 * Link to pthread (with `-pthread` on Linux/MAC/POSIX systems, or download the Windows version of pthread and use it)
 * Start coding!

Using the code is very simple. All you have to do is:

 * Create an object `ThreadPool_pthread pool(num)`, where num is the number of threads
 * Use the member function `pool.push_task(function, parameters)`, to add tasks to the pool, where `function` is a function pointer to the function to be added, and `parameters` is a `void*` that contains the parameters.
 * Call `pool.finish()`, which will block until all tasks are finished.

Note: Return values in the `function` are omitted.
Note: The function signature is `void* function(void* parameters)`.

### Makefiles

There's a make file that builds the example. There's also a qmake file that builds the example too.
