TtfxSubString? ttfxGetNextTextSubString(Pointer<TtfText> text, TtfxSubString subString)

Get the next substring in a text object

If called at the end of the text, this will return a zero length substring with the TTF_SUBSTRING_TEXT_END flag set.

\param text the TTF_Text to query. \param substring the TTF_SubString to query. \param next a pointer filled in with the next substring. \returns true on success or false on failure; call SDL_GetError() for more information.

Implementation

TtfxSubString? ttfxGetNextTextSubString(
  Pointer<TtfText> text,
  TtfxSubString subString,
) => ffi.using((arena) {
  final subStringPointer = subString.toNative(arena);
  final resultPointer = arena<TtfSubString>();

  if (ttfGetNextTextSubString(text, subStringPointer, resultPointer)) {
    return TtfxSubString.fromPointer(resultPointer);
  }
  return null;
});
