thread_pool_c

Thread pool written in C using the cross-platform threads.h library and atomic functions to control thread synchronization.

Dependencies

The project depends on gtest which is only needed when the build type is DEBUG. The dependency is automatically cloned using CMAKE

How to compile

cmake -DCMAKE_BUILD_TYPE=Debug -S . -B build
cmake --build build -j $(nproc)
ctest -j $(nproc) --test-dir build

Example:

void callback(void * data)
{
    atomic_uint_fast64_t * val = (atomic_uint_fast64_t *)data;
    printf("The atomic value is set to %ld\n", atomic_fetch_add(val, 1));
}

int main(void)
{
    atomic_uint_fast64_t * val = (atomic_uint_fast64_t *)calloc(1, sizeof(atomic_uint_fast64_t));
    
    thpool_t * thpool = thpool_init(4);

    for (int i = 0; i < 20; i++)
    {
        thpool_enqueue_job(thpool, callback, val);
    }

    thpool_wait(thpool);
    thpool_destroy(&thpool);
    free(val);
    return 0;
}
