WFONT-GET-CLOSEST-FONT (op-code 102)

This operation is identical to WFONT-GET-FONT, except that it doesn't fail if it cannot find the specified font. Instead, it returns the closest matching font. Note that only Windows systems are capable of performing this operation. On other systems, this call is treated as being identical to WFONT-GET-FONT. You should specify WFONT-CHAR-SET with this function to ensure that the returned font is useful. Also, specifying WFONT-FAMILY can help in locating a suitable font.
