Hello!
I'm relatively new to DJGPP, so forgive me if my question seems stupid. I
have a program in which I use some hardware interrupt handlers, and I don't
want to lock them individually for several reasons (e.g. they use way too
many variables). So I've decided to lock my program's code and data segments
entirely (the image size is not so large) but I don't want to lock any
additionally allocated memory. As I figure, the way to do it is something
like this:

#include <crt0.h>

int _crt0_startup_flags = _CRT0_FLAG_NONMOVE_SBRK | _CRT0_FLAG_LOCK_MEMORY;

int main(void)
{
    _crt0_startup_flags &= ~_CRT0_LOCK_MEMORY;
...

Am I right? If not, please someone tell me how I could do what I described
above.
Thank you.
