Breaking out of an infinite loop

ROOT
1

If a user inadvertently creates an infinite loop in their script is there anyway of breaking out of the loop from the keyboard, ie by pressing Ctrl-Break etc.

Also if I wanted to monitor a loop in the background and automatically breakout if the loop exceeded so many iterations is this possible ??

thanks

Hi David,

You can hit CTRL+C

Cheers,

Hello Philip

If I embed CINT using a DLL then does this break out key combination still apply or do I need to do something else ??

Regarding looping is there any way for the calling program to monitor loop activity in case the user creates a long or infinite loop ??

david

[quote]Regarding looping is there any way for the calling program to monitor loop activity in case the user creates a long or infinite loop ??[/quote]What do you have in mind? (The answer to the question is ‘yes’ and I am sure you can find many way in the literature/net on how this could be done but I do not have any good generic general purpose answer).
