The fn(vsprintf) function is equivalent to fn(sprintf), but with a type(va_list)
argument instead of variadic arguments. The argument arg(arg) must be
initialized with fnmacro(va_start) prior to calling fn(vsprintf). The
fn(vsprintf) function does not call fnmacro(va_end), so the calling function is
responsible for this.
