[ros-dev] runtime time function question in freeldr

[Zhang Fan]

Hi everybody,
I'm a newbie of ReactOS, and I've just looked a piece of code in freeldr module. I
found some runtime function such as strstr(). I want to know if the run time lib should be
initialized, and where the initialized code.
Another question is that a piece of code in arch.S


EXTERN(RealEntryPoint)

//....
	.code32

	/* Zero BootDrive and BootPartition */
	xorl	%eax,%eax
	movl	%eax,(_BootDrive)
	movl	%eax,(_BootPartition)

	/* Store the boot drive */
	movb	%dl,(_BootDrive)

	/* Store the boot partition */
	movb	%dh,(_BootPartition)

	/* GO! */
	pushl	%eax
	call	_BootMain

At there, I think %eax should equal zero, and BootMain will call CmdLineParse(),and
CmdLineParse will call strstr(). So it cause strstr will receive a NULL parameter. Is it
right?

Thank you.
