今天介绍C++ exception handling,stack unwinding的一个应用。Exception handling有多种ABI(interoperability of C++ implementations),其中应用最广泛的是Itanium C++ ABI: Exception Handling Itanium C++ ABI: Exception Handling 简化的exceptio
Exception handling is a mechanism in which a programming construct is used to consistently trap, intercept and handle the error occurred during application execution. The Common Language Runtime (CLR) of .NET Framework is designed to use an exception handling model based on exception objects and pr...
PROC FRAME [:ehandler]Causes MASM to generate a function table entry in .pdata and unwind information in .xdata for a function's structured exception handling unwind behavior. Ifehandleris present, this proc is entered in the .xdata as the language-specific handler. ...

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] (...

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...
Exceptions provide a clean way to check for errors without cluttering code, and a mechanism to signal errors directly rather than using flags or side effects that must be checked[38]. Exception handling is a mechanism for structuring the error-related code in a way that errors can be easily...

When handling a Reset exception, because the reset is exception type 1, the address of the reset vector is therefore 1×4 (each vector is 4 bytes)+VTOR, which equals 0x00000004. (2) When handling an NMI exception, the NMI vector (type 2) is located in 2×4+VTOR=0x00000008. ...
