ICLRSyncManager::GetRWLockOwnerNext Method

Gets the next IHostTask instance that is blocked on the current reader-writer lock.

HRESULT GetRWLockOwnerNext (
    [in] SIZE_T       Iterator,
    [out] IHostTask  *ppOwnerHostTask
);

Iterator

[in] The iterator that was created by using a call to CreateRWLockOwnerIterator.

ppOwnerHostTask

[out] A pointer to the next IHostTask that is waiting on the lock, or null if no task is waiting.

HRESULT

Description

S_OK

GetRWLockOwnerNext returned successfully.

HOST_E_CLRNOTAVAILABLE

The common language runtime (CLR) has not been loaded into a process, or the CLR is in a state in which it cannot run managed code or process the call successfully.

HOST_E_TIMEOUT

The call timed out.

HOST_E_NOT_OWNER

The caller does not own the lock.

HOST_E_ABANDONED

An event was canceled while a blocked thread or fiber was waiting on it.

E_FAIL

An unknown catastrophic failure occurred. When a method returns E_FAIL, the CLR is no longer usable within the process. Subsequent calls to hosting methods return HOST_E_CLRNOTAVAILABLE.

If ppOwnerHostTask is set to null, the iteration has terminated, and the host should call the DeleteRWLockOwnerIterator method.

Note Note

The CLR calls AddRef on the IHostTask to which ppOwnerHostTask points to prevent this task from exiting while the host holds the pointer. The host must call Release to decrement the reference count when it is finished.
