Nope. 3 things:

1) The syntax of the asm command is:

asm ("asm commands here" : invars : outvars: clobbered registeres);
I think. I don't use the asm command.

2) The converted code would look like this:

movl $13h, %eax
int $10h

3) You can't call real mode interrupts from a protected mode program. You can
try the following and it will work, though most people prefer to use the DPMI
calls for safety. This code is a little more portable.

#include <dos.h>

void set_mode13h()
{
    union REGS regs;
    regs.x.ax = 0x13;
    int86(0x10, &regs, &regs);
}
