Member Function Documentation

bool llvm::RWMutexImpl::reader_acquire ( )

Unconditionally acquire the lock in reader mode.

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.

Definition at line 77 of file RWMutex.cpp.

Referenced by llvm::sys::SmartRWMutex< mt_only >::reader_acquire().

bool llvm::RWMutexImpl::reader_release ( )

Unconditionally release the lock in reader mode.

Attempts to release the lock in reader mode.

Returns: false if any kind of error occurs, true otherwise.

Definition at line 87 of file RWMutex.cpp.

Referenced by llvm::sys::SmartRWMutex< mt_only >::reader_release().

bool llvm::RWMutexImpl::writer_acquire ( )

Unconditionally acquire the lock in writer mode.

Attempts to unconditionally acquire the lock in reader mode. If the lock is held by any readers, this method will wait until it can acquire the lock.

Returns: false if any kind of error occurs, true otherwise.

Definition at line 97 of file RWMutex.cpp.

Referenced by llvm::sys::SmartRWMutex< mt_only >::writer_acquire().

bool llvm::RWMutexImpl::writer_release ( )

Unconditionally release the lock in write mode.

Attempts to release the lock in writer mode.

Returns: false if any kind of error occurs, true otherwise.

Definition at line 107 of file RWMutex.cpp.
