Hi,
I am running root using a macro. At the end I want root to exit,
but all the commands I tried won't work. TSystem::Exit() and
TSystem::Abort() only give:
*** Break *** segmentation violation
I would be happy if somebody could explain me how I can get root to
exit when running a macro ?
Thanks for your help,
Carsten
PS: I saw in roottalk there was a similar question last year, but no
answer was given ... only a suggestion how it could be implemented in
root. I guess my question is, has anything happend since then ??
or has somebody thought of a workaround ?
This is last years answer:
>After 'exit()' is called, Cint stops doing anything. It sets
>a flag to block any statement as you observed. Because 'exit()'
>is normally used when process is terminated, this is a good behavior
>in most of the cases. However in ROOT, process is not terminated by
>exit(). It simply stops doing anything.
