PTHREAD_MUTEX_TRYLOCK(3) BSD Programmer's Manual PTHREAD_MUTEX_TRYLOCK(3)
pthread_mutex_trylock - attempt to lock a mutex without blocking
#include <pthread.h> int pthread_mutex_trylock(pthread_mutex_t *mutex);
The pthread_mutex_trylock() function locks mutex. If the mutex is already locked, pthread_mutex_trylock() will not block waiting for the mutex, but will return an error condition.
If successful, pthread_mutex_trylock() will return zero, otherwise an er- ror number will be returned to indicate the error.
pthread_mutex_trylock() will fail if: [EINVAL] The value specified by mutex is invalid. [EBUSY] mutex is already locked.
