Synchronization Functions (Windows CE 5.0)
The following table shows the kernel synchronization functions.
| Programming element | Description |
|---|---|
| CreateEvent | This function creates a named or an unnamed event object. |
| CreateMutex | This function creates a named or unnamed mutex object. |
| CreateSemaphore | This function creates a named or unnamed semaphore object. |
| DeleteCriticalSection | This function releases all resources used by a critical section object that is not owned. |
| DuplicateHandle | This function duplicates an object handle. The duplicate handle refers to the same object as the original handle. Therefore, any changes to the object are reflected through both handles. |
| EnterCriticalSection | This function waits for ownership of the specified critical section object. |
| InitializeCriticalSection | This function initializes a critical section object. |
| InterlockedCompareExchange | This function performs an atomic comparison of the specified values and exchanges the values based on the outcome of the comparison. |
| InterlockedCompareExchangePointer | This function performs an atomic comparison of the specified parameter values and exchanges the values based on the outcome of the comparison. |
| InterlockedDecrement | This function both decrements (decreases by one) the value of the specified 32-bit variable and checks the resulting value. |
| InterlockedExchange | This function atomically exchanges a pair of 32-bit values. |
| InterlockedExchangeAdd | This function performs an atomic addition of an increment value to an Addend variable. |
| InterlockedExchangePointer | This function atomically exchanges a pair of values. |
| InterlockedIncrement | This function both increments (increases by one) the value of the specified 32-bit variable and checks the resulting value. |
| InterlockedTestExchange | This function is an interlocked function that performs a conditional setting of a variable. |
| LeaveCriticalSection | This function releases ownership of the specified critical section object. |
| OpenEvent | This function opens an existing named event object. |
| PulseEvent | This function provides a single operation that sets to signaled the state of the specified event object and then resets it to nonsignaled after releasing the appropriate number of waiting threads. |
| ReleaseMutex | This function releases ownership of the specified mutex object. |
| ReleaseSemaphore | This function increases the count of the specified semaphore object by a specified amount. |
| ResetEvent | This function sets the state of the specified event object to nonsignaled. |
| SetEvent | This function sets the state of the specified event object to signaled. |
| TryEnterCriticalSection | This function attempts to enter a critical section without blocking. |
| WaitForMultipleObjects | This function returns when either any one of the specified objects is in the signaled state, or the time-out interval elapses. |
| WaitForSingleObject | This function returns when the specified object is in the signaled state or when the time-out interval elapses. |
