Threadpool is a small header-only threadpool implementation. It spawns a certain number of threads and executes tasks in parallel.
Unlike other implementations, threadpool does not use a container (such as std::vector<std::thread>). Instead, it spawns a certain number of threads, calls the detach() method and communicates with the threads using condition variables.
As a result, it is possible to resize the pool (by either adding or deleting threads) at runtime.
An example is provided to illustrate its usage. To run the example, do the following (assuming that the sources are located under ~/threadpool):
$ cd ~/threadpool
$ mkdir build && cd build && cmake .. && make
$ cd ../bin
$ ./threadpool
