IFont::ReleaseHfont method (ocidl.h)
Notifies the font object that the caller that previously locked this font in the cache with IFont::AddRefHfont no longer requires the lock.
HRESULT ReleaseHfont( [in] HFONT hFont );
A font handle previously realized through IFont::get_hFont. This value was passed to a previous call to IFont::AddRefHfont to lock the font, and the caller would now like to unlock the font in the cache.
The method supports the standard return values E_UNEXPECTED and E_INVALIDARG, as well as the following values.
||The font was unlocked successfully.|
||The font was not locked in the cache. This return value is a benign notification to the caller that it may have a font reference counting problem.|
