[sdcc-devel] z80 printf return value

[Felipe M. P. <Fel...@ic...>]

I made some modifications so printf returns the actual number of chars
written...

static int _char_count;  

STATIC void _char_emitter(char c, void *pData)
{
// ...
    _char_count++;
    putchar(c);
// ...
}

int printf(const char *format, ...)
{
// ...
    _char_count = 0;	 
    _printf(format, _char_emitter, NULL, va);
// ...
    /* PENDING: What to return? */
    return _char_count;
}

But this makes the function non reentrant.
