Expand description

Get the substring of a text object that contains the given line.

If line is less than 0, this will return a zero length substring at the beginning of the text with the TTF_SUBSTRING_TEXT_START flag set. If line

is greater than or equal to text->num_lines this will return a zero length substring at the end of the text with the TTF_SUBSTRING_TEXT_END flag set.

Parameter: text the TTF_Text to query.

Parameter: line a zero-based line index, in the range [0 .. text->num_lines-1].

Parameter: substring a pointer filled in with the substring containing the offset.

Returns: true on success or false on failure; call SDL_GetError() for more information.

Thread Safety: This function should be called on the thread that created the text.

Available Since: This function is available since SDL_ttf 3.0.0.
