Philosophers

thread ist tot

Special thank to amblanch, my goat 🐐🐐 for help me with helgrind and some data race.

Description

This project is a simulation of the dining philosophers problem, it using the pthread library to create threads and mutexes to synchronize them. the program takes 4 arguments:

• number_of_philosophers: the number of philosophers
• time_to_die: if a philosopher doesn't start eating time_to_die milliseconds after starting their last meal or the beginning of the simulation, they die.
• time_to_eat: the time it takes for a philosopher to eat. During that time, they will need to hold the two forks on their left and right.
• time_to_sleep: the time a philosopher will spend sleeping.
• eat_before_end (optional argument): if all philosophers eat at least eat_before_end times, the simulation stops. If not specified, the simulation stops when a philosopher dies.
