# al\_ustr\_next(3)

Allegro 5 API

## NAME

al\_ustr\_next - Allegro 5 API

## SYNOPSIS

-

  ```
  #include <allegro5/allegro.h>
  bool al_ustr_next(const ALLEGRO_USTR *us, int *pos)
  ```

## DESCRIPTION

Find the byte offset of the next code point in string, beginning at `*pos`. `*pos` does not have to be at the beginning of a code point.

Returns true on success, and the value pointed to by `pos` will be updated to the found offset. Otherwise returns false if `*pos` was already at the end of the string, and `*pos` is unmodified.

This function just looks for an appropriate byte; it doesn’t check if found offset is the beginning of a valid code point. If you are working with possibly invalid UTF-8 strings then it could skip over some invalid bytes.
