The following functions may be used to lock a mutex:
#include <pthread.h> int pthread_mutex_lock(pthread_mutex_t *mutex); int pthread_mutex_trylock(pthread_mutex_t *mutex); int pthread_mutex_timedlock (pthread_mutex_t *mutex, const struct timespec *restrict abs_timeout);
When locking a mutex the first option available to the user is pthread_mutex_lock, which has the following behavior on the thread:
If the mutex is not taken, the mutex is taken and the thread continues with its execution.
If the mutex lock is taken, the thread is blocked interrupting the thread execution.
The try_lock variant catches the mutex until it ends and with timedlock awaiting a maximum time.
