Function TTF_GetTextSubStringForLine 

pub unsafe extern "C" fn TTF_GetTextSubStringForLine(
    text: *mut TTF_Text,
    line: c_int,
    substring: *mut TTF_SubString,
) -> bool

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.

Parameters

• text: the TTF_Text to query.
• line: a zero-based line index, in the range [0 .. text->num_lines-1].
• substring: a pointer filled in with the substring containing the offset.

Return value

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.

Availability

This function is available since SDL_ttf 3.0.0.
