    libthreadar

    C++ library to manage threads and any type of exception between them

    Libthreadar is a C++ library providing an abstracted set of C++ *classes* to manipulate threads in a very simple and efficient way from your C++ code. It also handles exceptions thrown from a thread and propagated to another one, when the later is calling the thread::join() method. This let one manage exceptions as simply as it is in C++ single threaded context. Additionally, all the related objects around multi-threading (mutex, semaphore, ...) are provided, under easy to use and independent C++ classes. Other more advanced classes ease the information exchange between threads like scattering and gathering a collection of objects between many threads, or asynchonous buffered information exchanges between two threads. All these C++ classes are easy to use and fully documented
