======

Declare the pointer for the pools data, memory is malloc'd when you create the pool: 

thread_pool_t *pool_id;

Create the pool, returns 0 if the pool is created or POOL_CREATE_ERR otherwise.  Mode is either CTP_PRIORITY,
 CTP_FIFO (first in, first out) or FILO (first in, last out):

ctp_create_pool(&pool_id, min_threads, max_threads, mode);

Add a job to the pool, priority is 1 first, 99 last (ignored if mode is CTP_PRIORITY), *data must be a 
pointer to already malloc'd memory, returns 0 if the job is added, JOB_CREATE_ERR otherwise.  *data must be free'd before the function end:

ctp_add_job(pool_id, priority, *function, *data);

Kill the pool, destorys all jobs & threads, after already running jobs finish, returns 0 when the pool is killed:

ctp_kill_pool(&pool_id);

Pause/start the pool, already running jobs continue, no new jobs are started:

ctp_pause_pool(pool_id);
ctp_start_pool(pool_id);

Change max/min threads:

ctp_max_threads(pool_id, max_threads);
ctp_min_threads(pool_id, min_threads);

POOL_DEAD is returned by ctp_add_job, ctp_kill_pool, ctp_pause_pool, ctp_start_pool, ctp_max_threads &
 ctp_min_threads if a null pointer is passed to them
