Exception is a rather overloaded word in software development. If you mean C++ exceptions (the only thing you can catch with a C++ catch), those can only be thrown with the throw keyword; everything else is not portable.

Hi guys,
I am looking to complete cross platform implementation of enabling/disabling logic in boost::execution_monitor. It looks like there is no standard interface available. I'm using _controlfp interface now on Windows. I also found these non-standard extensions:
* feenableexcep/fedisableexcept available with glib 2.2 * fesettrapenable avaialble in Dinkumware (implementation of STL?) and HP * sun has something called fex_set_handling. not sure when it's available though * header fpu_control.h. Not sure where it's available though. * MAC OS X has something called _MM_SET_EXCEPTION_MASK in xmmintrin.h
It also seems that in some cases the switch is compile time only (using compilation option).
Would anyone care to extend this list/comment on it's applicability and/or correctness?
Another change I am considering is to split floating point exception catching from other system exceptions. It seems perfectly valid scenario to set catch_system_error to false (thus avoid catching access violations etc) but still willing to catch and process floating point exception. What do you think?
