Exception Vs Error Code C


It requires consistent RAII, but that's how you should write anyway. Any advice? :) c++ exception error-handling assert share|improve this question edited Sep 7 '09 at 12:20 asked Sep 7 '09 at 9:00 Andrew M Look at the related questions If my compiler barfs and leaves a partially written out object file, it's a "logical disaster" because now the build system will think that the object file is available and barf Error codes have another horrible anti-debugging quality: loss of information. his comment is here

return 0; } int f7() { // ... Confusing logical errors with runtime situations: For example, suppose you have a function f(Foo* p) that must never be called with nullptr. For example, if object x is inaccessible to the scope of the catch clause, such as when it's buried in the private part of some class or is static within some By doing this, we turn the super difficult "Reverse the Flow of Time" error handling into the super easy "Get the Hell out of Dodge" error handling. http://stackoverflow.com/questions/253314/exceptions-or-error-codes

Exception Error Code Java

Don't try to force a framework into your way of thinking, even if "your" way of thinking is "better." If you decide to use a framework, embrace its way of thinking This results maintainability and debugging difficulties. I say pick up what best integrates with the clients of your library. share|improve this answer answered Oct 31 '08 at 12:48 Pistos 13.4k84466 +1 for the pointers and insight. –Jorge Ferreira Oct 31 '08 at 12:50 add a comment| up vote

Additionally, if you can't handle the exception where it occurred, and must pass it up the stack to a UI, (or worse, across the wire from a mid-tier component to a C++ Copy #include #include #include using namespace std; class MyClass { public: void MyFunc(char c) { if(c < numeric_limits::max()) throw invalid_argument("MyFunc argument too large."); //... } }; int If you raise Exceptions, this will usually make it easier for clients to migrate to a newer version of a library. you could check here Dobb's Thriving Among the APIs The Long Death of Project Hosting Sites Testing for Failures with Python Most Popular Stories Blogs RESTful Web Services: A Tutorial iOS Data Storage: Core Data

There is no point in handling such an error by using an exception because the error indicates that something in the code has to be fixed, and doesn't represent a condition C++ Error Codes You throw an exception. Another win for whoever gets to debug the code. Your contrived example looks somewhat deceptive, but consider if there were several interleaved function calls and variable increments.

The availability of exceptions may encourage developers to throw them when they are not appropriate or recover from them when it's not safe to do so. https://msdn.microsoft.com/en-us/library/hh279678.aspx In large systems, exception hierarchies must be designed with a system-wide mindset.
