Hi,
>>>>>>>> Is there any way in DJGPP to disable all interrupts :
I want to write function like :

void critical_error(int code) {
  disable_interrupts(); // ???
  textmode(C80);
  /*...*/
  _exit(code);
}

I need to disable interrupts, because, if interrupts will remain active,
then for example Allegro mouse redrawing routine will cause error.
This critical_error() function will be used, when my program will become
unstable (like out of memory etc...) so I don't want any other interrupts to
continue working, because they will probably cause other problems.

>>>>>>>>> Is there way to re-enable interrupts ?
It'll be useful in making something like Windows "blue screen"
