#if defined( _MSC_VER )
#define asm __asm
#endif
int
is_ansi (void)
{
static int hasAnsi = -1;
if (hasAnsi == -1)
{
asm {
asm mov ax,0x1a00
asm int 0x2f
asm cmp al,0xff
asm mov ax,0
asm jnz noAnsi
asm inc ax
noAnsi:
hasAnsi = _AX;
}
}
return hasAnsi;
}
Works with DOS 4.0 or above.

Yep.

No, not via printf() anyway.
