Member Function Documentation

void CArchMultithreadWindows::broadcastCondVar ( CArchCond   )  [virtual]

Broadcast a condition variable.

Broadcasting a condition variable releases all waiting threads.

Implements IArchMultithread.

Definition at line 189 of file CArchMultithreadWindows.cpp.

References lockMutex(), CArchCondImpl::m_events, CArchCondImpl::m_waitCount, CArchCondImpl::m_waitCountMutex, and unlockMutex().

void CArchMultithreadWindows::cancelThread ( CArchThread   )  [virtual]

Force a thread to exit.

Causes thread to exit when it next calls a cancellation point. A thread avoids cancellation as long as it nevers calls a cancellation point. Once it begins the cancellation process it must always let cancellation go to completion but may take as long as necessary to clean up.

Implements IArchMultithread.

Definition at line 366 of file CArchMultithreadWindows.cpp.

References CArchThreadImpl::m_cancel.

void CArchMultithreadWindows::closeThread ( CArchThread   )  [virtual]

Release a thread reference.

Deletes the given thread object. This does not destroy the thread the object referred to, even if there are no remaining references. Use cancelThread() and waitThread() to stop a thread and wait for it to exit.

Implements IArchMultithread.

Definition at line 336 of file CArchMultithreadWindows.cpp.

References lockMutex(), CArchThreadImpl::m_id, CArchThreadImpl::m_refCount, CArchThreadImpl::m_thread, and unlockMutex().

Referenced by wait().

CArchThread CArchMultithreadWindows::copyThread ( CArchThread   )  [virtual]

Copy a thread object.

Returns a reference to to thread referred to by thread.

Implements IArchMultithread.

Definition at line 359 of file CArchMultithreadWindows.cpp.

IArchMultithread::ThreadID CArchMultithreadWindows::getIDOfThread ( CArchThread   )  [virtual]

Returns an ID for a thread.

Returns some ID number for thread. This is for logging purposes. All thread objects referring to the same thread return the same ID. However, clients should us isSameThread() to compare thread objects instead of comparing IDs.

Implements IArchMultithread.

Definition at line 530 of file CArchMultithreadWindows.cpp.

References CArchThreadImpl::m_id.

void * CArchMultithreadWindows::getResultOfThread ( CArchThread   )  [virtual]

Returns the exit code of a thread.

Waits indefinitely for thread to exit (if it hasn't yet) then returns the thread's exit code.

(Cancellation point)

Implements IArchMultithread.

Definition at line 521 of file CArchMultithreadWindows.cpp.

References lockMutex(), CArchThreadImpl::m_result, and unlockMutex().

bool CArchMultithreadWindows::isExitedThread ( CArchThread   )  [virtual]

Test if thread exited.

Returns true iff thread has exited.

Implements IArchMultithread.

Definition at line 514 of file CArchMultithreadWindows.cpp.

References CArchThreadImpl::m_exit.

bool CArchMultithreadWindows::isSameThread ( CArchThread  ,
CArchThread   
) [virtual]

Compare threads.

Returns true iff two thread objects refer to the same thread. Note that comparing thread objects directly is meaningless.

Implements IArchMultithread.

Definition at line 508 of file CArchMultithreadWindows.cpp.

CArchCond CArchMultithreadWindows::newCondVar (  )  [virtual]

Create a condition variable.

The condition variable is an opaque data type.

Implements IArchMultithread.

Definition at line 153 of file CArchMultithreadWindows.cpp.

References CArchCondImpl::m_events, CArchCondImpl::m_waitCount, CArchCondImpl::m_waitCountMutex, and newMutex().

CArchThread CArchMultithreadWindows::newCurrentThread (  )  [virtual]

Get a reference to the calling thread.

Returns a thread representing the current (i.e. calling) thread.

Implements IArchMultithread.

Definition at line 326 of file CArchMultithreadWindows.cpp.

References lockMutex(), and unlockMutex().

CArchMutex CArchMultithreadWindows::newMutex (  )  [virtual]

Create a recursive mutex.

Creates a recursive mutex. A thread may lock a recursive mutex when it already holds a lock on that mutex. The mutex is an opaque data type.

Implements IArchMultithread.

Definition at line 263 of file CArchMultithreadWindows.cpp.

References CArchMutexImpl::m_mutex.

void CArchMultithreadWindows::setPriorityOfThread ( CArchThread  ,
int  n 
) [virtual]

Change thread priority.

Changes the priority of thread by n. If n is positive the thread has a lower priority and if negative a higher priority. Some architectures may not support either or both directions.

Implements IArchMultithread.

Definition at line 375 of file CArchMultithreadWindows.cpp.

References CArchThreadImpl::m_thread.

void CArchMultithreadWindows::signalCondVar ( CArchCond   )  [virtual]

Signal a condition variable.

Signalling a condition variable releases one waiting thread.

Implements IArchMultithread.

Definition at line 175 of file CArchMultithreadWindows.cpp.

References lockMutex(), CArchCondImpl::m_events, CArchCondImpl::m_waitCount, CArchCondImpl::m_waitCountMutex, and unlockMutex().

void CArchMultithreadWindows::testCancelThread (  )  [virtual]

Cancellation point.

This method does nothing but is a cancellation point. Clients can make their own functions cancellation points by calling this method at appropriate times.

(Cancellation point)

Implements IArchMultithread.

Definition at line 434 of file CArchMultithreadWindows.cpp.

References lockMutex(), and unlockMutex().

bool CArchMultithreadWindows::wait ( CArchThread  ,
double  timeout 
) [virtual]

Wait for a thread to exit.

Waits for up to timeout seconds for thread to exit (normally or by cancellation). Waits forever if timeout < 0. Returns true if the thread exited, false otherwise. Waiting on the current thread returns immediately with false.

(Cancellation point)

Implements IArchMultithread.

Definition at line 446 of file CArchMultithreadWindows.cpp.

References closeThread(), lockMutex(), CArchThreadImpl::m_exit, and unlockMutex().

bool CArchMultithreadWindows::waitCondVar ( CArchCond  ,
CArchMutex  ,
double  timeout 
) [virtual]

Wait on a condition variable.

Wait on a conditation variable for up to timeout seconds. If timeout is < 0 then there is no timeout. The mutex must be locked when this method is called. The mutex is unlocked during the wait and locked again before returning. Returns true if the condition variable was signalled and false on timeout.

(Cancellation point)

Implements IArchMultithread.
