NAME
       al_ustr_vappendf - Allegro 5 API


SYNOPSIS
              #include <allegro5/allegro.h>

              bool al_ustr_vappendf(ALLEGRO_USTR *us, const char *fmt, va_list ap)


DESCRIPTION
       Like al_ustr_appendf(3alleg5) but you pass the variable argument list directly, instead of
       the arguments themselves.  See al_ustr_newf(3alleg5) about the "%s" and "%c" specifiers.

       Returns true on success, false on error.
