Synchronization Functions (Compact 2013)

August 12, 2016

The following table shows the kernel synchronization functions.

Functions	Description
CeAcquireRwLock	Requests either shared or exclusive access to a reader/writer lock.
CeCreateRwLock	Creates a reader/writer lock.
CeDeleteRwLock	Deletes the specified reader/writer lock object.
CeIsRwLockAcquired	Determines whether the calling thread holds a specified reader/writer lock.
CeReleaseRwLock	Releases either shared or exclusive access to a reader/writer lock.
CreateEvent	Creates a named or an unnamed event object.
CreateMutex	Creates a named or unnamed mutex object.
CreateSemaphore	Creates a named or unnamed semaphore object.
DeleteCriticalSection	Releases all resources used by a critical section object that is not owned.
DuplicateHandle	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	Waits for ownership of the specified critical section object.
InitializeCriticalSection	Initializes a critical section object.
InterlockedCompareExchange	Performs an atomic comparison of the specified values and exchanges the values based on the outcome of the comparison.
InterlockedCompareExchangePointer	Performs an atomic comparison of the specified parameter values and exchanges the values based on the outcome of the comparison.
InterlockedDecrement	Decrements the value of the specified 32-bit variable, and checks the resulting value.
InterlockedExchange	Exchanges a pair of 32-bit values.
InterlockedExchangeAdd	Increments an Addend variable.
InterlockedExchangePointer	Exchanges a pair of values.
InterlockedIncrement	Increments the value of the specified 32-bit variable, and checks the resulting value.
InterlockedTestExchange	Performs a conditional setting of a variable.
LeaveCriticalSection	Releases ownership of the specified critical section object.
OpenEvent	Opens an existing named event object.
PulseEvent	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	Releases ownership of the specified mutex object.
ReleaseSemaphore	Increases the count of the specified semaphore object by a specified amount.
ResetEvent	Sets the state of the specified event object to nonsignaled.
SetEvent	Sets the state of the specified event object to signaled.
TryEnterCriticalSection	Tries to enter a critical section without blocking.
WaitForMultipleObjects	Returns when either any one of the specified objects is in the signaled state, or the time-out interval elapses.
WaitForSingleObject	Returns when the specified object is in the signaled state or when the time-out interval elapses.
