Syntax

BOOL
  CeIsRwLockAcquired(
    __in HRWLOCK   hLock,
    __in CERW_TYPE typeLock
  );

Parameters

  • hLock
    [in] Handle to a reader/writer lock object created by a call to CeCreateRwLock.
  • typeLock
    [in] Specifies the type of access, either CERW_TYPE_SHARED or CERW_TYPE_EXCLUSIVE, to check against the specified lock.

Return Value

TRUE indicates the lock is valid and the calling thread holds the specified access to the lock. FALSE indicates the lock is invalid, or the calling thread does not hold the specified access to the lock. To get extended error information, call GetLastError.
