Copied!

ADLX_RESULT     GetDisplayChangedHandling (IADLXDisplayChangedHandling ** ppDisplayChangedHandling)

Parameters

  1. [in] ppDisplayChangedHandling IADLXDisplayChangedHandling ** The address of a pointer to the returned interface. If the interface is not successfully returned, the method sets the dereferenced address *ppDisplayChangedHandling to nullptr.

Return Value

If the interface is successfully returned, ADLX_OK is returned.

If the interface is not successfully returned, an error code is returned.

Refer to ADLX_RESULT for success codes and error codes.

Remarks

The returned interface must be discarded with Release when it is no longer needed.

Additional Info

In C++ when using a smart pointer for the display changing listener interface there is no need to call Release because the smart pointer calls it internally.
