Hi Thomas, You can also implement your own error handler. See base/src/TError.cxx for an example (which happens to be the default). In your replacement you throw any exception you want. We can not quite yet move to exception since at least one experiment still uses an compiler option removing support for exception (this should change earlier 2004) Cheers, Philippe. PS. To set a break point in gdb just type break `Error(<tab>` -----Original Message----- From: Thomas Bretz [mailto:tbretz@astro.uni-wuerzburg.de] Sent: Tuesday, September 30, 2003 10:29 AM To: Philippe Canal Cc: roottalk@pcroot.cern.ch Subject: Re: [ROOT] Error and Exceptions Hi Philippe, yes, you might be right, but this means, that I have to read the gdb manual ;-)) Another advantage would be, that I can make sure, that in such a case my program stops. Otherwise I could create results - not recognizing the warning - which are wrong... Thomas.
