pthread_mutex_trylock -- attempt to lock a mutex without blocking LIBRARY
POSIX Threads Library (libpthread, -lpthread) SYNOPSIS
#include <pthread.h> int pthread_mutex_trylock(pthread_mutex_t *mutex); DESCRIPTION
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. RETURN VALUES
If successful, pthread_mutex_trylock() will return zero, otherwise an error number will be returned to indicate the error. ERRORS
The pthread_mutex_trylock() function will fail if: [EINVAL] The value specified by mutex is invalid. [EBUSY] Mutex is already locked. SEE ALSO
