Try this :

main () {
	_go32_dpmi_seginfo old_handler, my_handler;

	printf ("Getting old I-Vector !\n");
	_go32_dpmi_get_protected_mode_interrupt_vector (9, &old_handler);

	my_handler.pm_offset = (int) keyb_handler;
//******Add this line \/
	my_handler.pm_selector = _go32_my_cs();
//******Delete this line \/
//******_go32_dpmi_allocate_iret_wrapper (&my_handler);

	printf("\nSeting new I-Vector !");
//******And change _go32_dpmi_set... with _go32_dpmi_chain...
	_go32_dpmi_chain_protected_mode_interrupt_vector (9, &my_handler);

	printf("\nDONE !!\n\nWaiting now 20 seconds for testing.\n");
	sleep (20);
	_go32_dpmi_set_protected_mode_interrupt_vector (9, &old_handler);

	printf("\n\nOld I-Vector restored ;)\nEnd");
	return 0;
}

For the solution, just read help file for _go32_dpmi_set... with INFO ;)

Bye
