IAccessor::AddRefAccessor

Adds a reference count to an existing accessor.

HRESULT AddRefAccessor (
   HACCESSOR   hAccessor,
   DBREFCOUNT *pcRefCount);

Parameters

hAccessor: [in]
The handle of the accessor for which to increment the reference count.
pcRefCount: [out]
A pointer to memory in which to return the reference count of the accessor handle. If pcRefCount is a null pointer, no reference count is returned.

Return Code

S_OK: The method succeeded.
E_FAIL: A provider-specific error occurred.
E_UNEXPECTED: ITransaction::Commit or ITransaction::Abort was called, and the object is in a zombie state. This error can be returned only when the method is called on a rowset.
DB_E_BADACCESSORHANDLE: hAccessor was invalid.

Comments

The consumer must increment the reference count on an accessor by calling IAccessor::AddRefAccessor before passing it to another thread.
