Member Function Documentation

◆ operator=()

RWMutexImpl& llvm::sys::RWMutexImpl::operator= ( const RWMutexImpl )
delete

◆ reader_acquire()

bool RWMutexImpl::reader_acquire ( )

Attempts to unconditionally acquire the lock in reader mode.

If the lock is held by a writer, this method will wait until it can acquire the lock.

Returns
false if any kind of error occurs, true otherwise. Unconditionally acquire the lock in reader mode.

◆ reader_release()

bool RWMutexImpl::reader_release ( )

Attempts to release the lock in reader mode.

Returns
false if any kind of error occurs, true otherwise. Unconditionally release the lock in reader mode.

◆ writer_acquire()

bool RWMutexImpl::writer_acquire ( )
