ttfGetPreviousTextSubString function ttf

bool ttfGetPreviousTextSubString(Pointer<TtfText> text, Pointer<TtfSubString> substring, Pointer<TtfSubString> previous)

Get the previous substring in a text object

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

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

\threadsafety This function should be called on the thread that created the text.

\since This function is available since SDL_ttf 3.0.0.
