ICAbout macro

The ICAbout macro notifies a video compression driver to display its About dialog box. You can use this macro or explicitly call the ICM_ABOUT message.

Syntax


DWORD ICAbout(
    hic,
    hwnd
);

Parameters

hic

hwnd

Returns ICERR_OK if the driver supports this message or ICERR_UNSUPPORTED otherwise.
