From what I understand, the following should print "Hello, world." on stdout. I stole the code from the Linux HOWTO, but I think it should work on FreeBSD as well. Instead, the call to write returns 9 (EBADF). .data msg: .string "Hello, world.\n" len = . - msg - 1 .text global _start _start: movl $4, %eax movl $1, %ebx movl $msg, %ecx movl $len, %edx int $0x80 movl $1, %eax xorl %ebx, %ebx int $0x80 Can anyone explain what I've done wrong? As a related question, can anyone point me to the source for the int 0x80 handler? I've looked all over but can't find it. Thanks.
