Defined in SDL3_ttf/SDL_ttf.h

#include "SDL3_ttf/SDL_ttf.h"

bool TTF_InsertTextString(TTF_Text *text, int offset, const char *string, size_t length);

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

text: the TTF_Text
to modify.
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.
string: the UTF-8 text to insert.
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.

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

This function is available since SDL_ttf 3.0.0.
