I could be wrong, but "C" language doesn't have exception. Did you compiled "C" code with "C++" compiler? > I have managed to handle exceptions on Windows catching the WindowsError. > > However, whenever my Linux code throws an exception, I never get a chance to > recover. Is this documented anywhere? The internal ( OS ) mechanism is very different between Windows and Linux. Linux will send you signal. It is possible to convert that signal to exception, but the resulting code is very very fragile and it is not portable. If you can't change the function ( to report the error via in-out argument ), then you can create a function wrapper and convert exception to some else.
