2388 This function iterates through fonts which match the specified font, using
2389 the specified criteria. If String is non-NULL, then all of the characters in
2390 the string must exist in order for a candidate font to be returned.
2392 @param This A pointer to the EFI_HII_FONT_PROTOCOL instance.
2393 @param FontHandle On entry, points to the font handle returned by a
2394 previous call to GetFontInfo() or NULL to start
2395 with the first font. On return, points to the
2396 returned font handle or points to NULL if there
2397 are no more matching fonts.
2398 @param StringInfoIn Upon entry, points to the font to return
2400 If NULL, then the information about the system default
2401 font will be returned.
2402 @param StringInfoOut Upon return, contains the matching font's
2403 information. If NULL, then no information is
2404 returned. It's caller's responsibility to free
2406 @param String Points to the string which will be tested to
2407 determine if all characters are available. If
2408 NULL, then any font is acceptable.
