Source 
pub unsafe extern "C" fn TTF_InsertTextString(

Expand description

Insert UTF-8 text into a text object.

This function may cause the internal text representation to be rebuilt.

Parameter: text the TTF_Text to modify.

Parameter: offset the offset, in bytes, from the beginning of the string if >= 0, the offset from the end of the string if < 0. Note that this does not do UTF-8 validation, so you should only insert at UTF-8 sequence boundaries.

Parameter: string the UTF-8 text to insert.

Parameter: length the length of the text, in bytes, or 0 for null terminated text.

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.
