c language thread pool

use

build your executable file with worker_pool.c -lpthread

first step, create worker pool with worker num, which will effect your concurrence.

worker_pool *wp =  create_worker_pool(worker_num);

second, add task which you want to execute async.

add_task(wp, execute_func, data);

finally, destroy your worker_pool.

destroy_worker_pool(wp);

extra, monitor run status.

dump_worker_pool_status(worker_pool *wp);

gcc -std=gnu99 -o main test.c worker_pool.c -lpthread
./main

output:

start worker 1
start worker 2
end worker 2
start worker 1
start worker 2
end worker 2
start worker 1
start worker 2

some action use pthread_barrier_* functions to sync data without lock.
