al_ustr_prev(3)						       al_ustr_prev(3)

NAME
       al_ustr_prev - Allegro 5	API

SYNOPSIS
	      #include <allegro5/allegro.h>

	      bool al_ustr_prev(const ALLEGRO_USTR *us,	int *pos)

DESCRIPTION
       Find the	byte offset of the previous code point in string, before *pos.
       *pos does not have to be	at the beginning of  a	code  point.   Returns
       true  on	 success,  then	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, then *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	 work-
       ing  with  possibly  invalid UTF-8 strings then it could	skip over some
       invalid bytes.
