class Mutex

class Mutex

Defined at line 18 of file ../../zircon/system/ulib/sync/include/lib/sync/cpp/mutex.h

C++ wrapper around |sync_mutex_t|. This can be more efficient than the

standard C |mtx_t| or C++ |std::mutex|.

It satisfies the BasicLockable C++ requirement.

void lock ()

Locks the mutex.

The current thread will block until the mutex is acquired. The mutex is

non-recursive, which means attempting to lock a mutex that is already held by

this thread will deadlock.

Defined at line 32 of file ../../zircon/system/ulib/sync/include/lib/sync/cpp/mutex.h

bool try_lock ()

Attempts to lock the mutex without blocking.

Returns true if the lock is obtained, and false if not.

Defined at line 37 of file ../../zircon/system/ulib/sync/include/lib/sync/cpp/mutex.h

void unlock ()

Unlocks the mutex.

Do not unlock the mutex again if it is already unlocked. Do not rely

on any behavior from duplicated unlocking.

sync_mutex_t * get ()

Returns the wrapped |sync_mutex_t|.
