• This function must call the font mapper internally to find the closest match to the LOGFONT, when CF_INITTOLOGFONTSTRUCT option flag is specified.

• This function must exclude both Windows vertical writing fonts (@facename) and the Postscript vertical writing fonts (facename-V, facename-V-some) from the list, when CF_NOVERTFONT option flag is specified.
See The Metrics Mapping and The Font Mapper for details.
