Hi
I got a problem with inline asm example from some tutor. The source looks like:

int main()
{
    __asm__("
        xorl %ebx,%ebx
        movb $0x17,%al
        int $0x80
    ");
 return 0;
}

And now i got an error:
apacz@dstool:~/coding/tests/bo$ gcc asm.c
asm.c:3:17: missing terminating " character
asm.c: In function `main':
asm.c:4: error: parse error before "xorl"
asm.c:7:9: missing terminating " character

It should be fine couse it's from tutor.. Why something like this appears?

apacz,
Regards.

Ok, it's solved. Maybe it ll be helpful for others:
In this case it should looks like:

(Toggle Plain Text)

int main()
{
    __asm__(
        "xorl %ebx,%ebx\n"
        "movb $0x17,%al\n"
        "int $0x80\n"
    );
 return 0;
}
