Win32 implementation of IArchMultithread.
Definition at line 45 of file CArchMultithreadWindows.h.
| void CArchMultithreadWindows::broadcastCondVar | ( | CArchCond | ) | [virtual] |
Broadcast a condition variable.
Broadcasting a condition variable releases all waiting threads.
Implements IArchMultithread.
Definition at line 193 of file CArchMultithreadWindows.cpp.
References lockMutex(), and unlockMutex().
| void CArchMultithreadWindows::cancelThread | ( | CArchThread | thread | ) | [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 370 of file CArchMultithreadWindows.cpp.
| 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.

| CArchThread CArchMultithreadWindows::copyThread | ( | CArchThread | thread | ) | [virtual] |
Copy a thread object.
Returns a reference to to thread referred to by thread.
Implements IArchMultithread.
Definition at line 363 of file CArchMultithreadWindows.cpp.
| IArchMultithread::ThreadID CArchMultithreadWindows::getIDOfThread | ( | CArchThread | thread | ) | [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 534 of file CArchMultithreadWindows.cpp.
| void * CArchMultithreadWindows::getResultOfThread | ( | CArchThread | thread | ) | [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.

References lockMutex(), and unlockMutex().
| bool CArchMultithreadWindows::isExitedThread | ( | CArchThread | thread | ) | [virtual] |
Test if thread exited.
Returns true iff thread has exited.
Implements IArchMultithread.
Definition at line 518 of file CArchMultithreadWindows.cpp.
| 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 512 of file CArchMultithreadWindows.cpp.
| CArchCond CArchMultithreadWindows::newCondVar | ( | ) | [virtual] |
Create a condition variable.
The condition variable is an opaque data type.
Implements IArchMultithread.

References newMutex().
| CArchThread CArchMultithreadWindows::newCurrentThread | ( | ) | [virtual] |
Get a reference to the calling thread.
Returns a thread representing the current (i.e. calling) thread.
Implements IArchMultithread.

| 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.

| CArchThread CArchMultithreadWindows::newThread | ( | ThreadFunc | func, | |
| void * | userData | |||
| ) | [virtual] |
Start a new thread.
Creates and starts a new thread, using func as the entry point and passing it userData. The thread is an opaque data type.
Implements IArchMultithread.

| void CArchMultithreadWindows::raiseSignal | ( | ESignal | signal | ) | [virtual] |
Invoke the signal handler.
Invokes the signal handler for signal, if any. If no handler cancels the main thread for kINTERRUPT and kTERMINATE and ignores the call otherwise.
Implements IArchMultithread.
Definition at line 550 of file CArchMultithreadWindows.cpp.
References IArchMultithread::kINTERRUPT, IArchMultithread::kTERMINATE, lockMutex(), and unlockMutex().
| 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 379 of file CArchMultithreadWindows.cpp.
| void CArchMultithreadWindows::setSignalHandler | ( | ESignal | , | |
| SignalFunc | func, | |||
| void * | userData | |||
| ) | [virtual] |
Set the interrupt handler.
Sets the function to call on receipt of an external interrupt. By default and when func is NULL, the main thread is cancelled.
Implements IArchMultithread.

| void CArchMultithreadWindows::signalCondVar | ( | CArchCond | ) | [virtual] |
Signal a condition variable.
Signalling a condition variable releases one waiting thread.

References lockMutex(), 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)

| bool CArchMultithreadWindows::wait | ( | CArchThread | thread, | |
| 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.

| 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.
