ft_contrast is a 42 rush project (project realised on a week-end) consisting in building a threadpool library and three different programs applying a contrast on a picture.
| Program | Description |
|---|---|
| ft_contrast | A simple contrast program |
| ft_contrast_th | A contrast program using multithreading |
| ft_contrast_tp | A contrast program using the multithreading pool (from tpool library) |
All the programs must be used with an input file, an output file and a contrast.
./ft_contrast_tp -f imgs/hands.pgm -c 50 -o out.pgm
libtpool has three different functions to create a threadpool, add tasks and wait for all the tasks to be done.
t_tpool *tp_create(int nb_threads);
void tp_exec_queue_add(void *args, void (*func)(void*));
void tp_wait_for_queue(void);
