Usage
-
#include <allegro5/allegro.h> int al_ustr_offset(const ALLEGRO_USTR *us, int index)
Overview
Return the byte offset (from the start of the string) of the code point at the specified index in the string. A zero index parameter will return the first character of the string. If index is negative, it counts backward from the end of the string, so an index of -1 will return an offset to the last code point.
If the index is past the end of the string, returns the offset of the end of the string.
