A recursive mutex that guarantees order of obtainment using a first-in, first-out (FIFO) scheduling mechanism.

Constructor

os_fifo_mutex( bool locked )

Constructs a mutex with an initial locked (default false ) state.

Throws: os_thread_toolkit_error

Destructor

~os_fifo_mutex()

Destroys this mutex.

lock

void lock()

Acquires a lock, blocking if necessary. Multiple locks can be obtained by the same thread.

Throws: os_thread_toolkit_error

obtain

void obtain()

Synonym for lock() ; alternative acquisition syntax.

Throws: os_thread_toolkit_error

release

void release()

Synonym for unlock() ; alternative acquisition syntax.

Throws: os_thread_toolkit_error

try_lock

bool try_lock()

Attempts to acquire a lock without blocking. Returns true if successful.

Throws: os_thread_toolkit_error

unlock

void unlock()

Releases a single lock. If a thread owns multiple locks, an equal number of unlocks must occur before the mutex becomes available.
