Exception handling in C++ is a mechanism that allows a program to handle errors or exceptional situations during runtime by using try, catch, and throw statements.
I will refer to this structure as funcinfo and talk more about it in the next section. Figure 4 shows a broader picture of how things look like at runtime when considering exception handling. Widget's exception callback is at the head of the exception chain pointed to by FS:[0] (...
Operating system gets the next node off the exception handling list and calls its exception handler (which is the handler for the caller of the current function). This continues until the exception handler finds the catch block interested in catching the exception in which case it does not ...
After this point, any exception that occurs with in the program - from throwing an exception to stack unwinding, calling the catch block and then resuming the execution - is processed by my exception handling library. The C++ standard, like any other feature in C++, doesn't say anything abou...
The C++ standard, like any other feature in C++, doesn't say anything about how exception handling should be implemented. This means that every vendor is free to use any implementation as he sees fit. I will describe how VC++ implements this feature, but it should be a good study material...
(); ``` Here, if the constructor failed, memory of *p will not leak. But, any memory allocated inside the constructor's body will leak ( that's why it's recommended to use smart pointers here ) 3. Throwing exceptions from constructor and handling them inside the caller's body should ...
So you have to install exception handlers in each thread. Each module (EXE or DLL) in your application is linked to CRT libraries (either statically or dynamically). Exception handling techniques strongly depend on the CRT linkage type. The variety of error types, differences of handling ...

Introduction One of the revolutionary features of C++ over traditional languages is its support for exception handling. It provides a very good alternative to traditional techniques...
A robust exception-handling policy requires careful thought and should be part of the design process. In general, most exceptions are detected and thrown at the lower layers of a software module, but typically these layers do not have enough context to handle the error or expose a message to...
The real power of C++ exception handling lies not only in its ability to deal with exceptions of varying types, but also in its ability to automatically call destructor functions during stack unwinding for all local objects constructed before the exception was thrown. ...
