How to Define New Exceptions in CPP? To define a new exception in C++, you can follow these steps: Decide on the type of exception you want to create. You can either derive your exception class from the standard exception class provided by the C++ Standard Library or create a custom excep...
3) By contrast, runtime errors are due to events beyond the scope of the program. They cannot be easily predicted in advance. 程序的作用范围造成的( the "scope" is defined as the library code's expectations, not your program's design) 在Cpp标准上也有这样的描述: logic_error: "The class...
As long as the OS-dependent functions for TLS data are defined (in our example, we just use a single global variable), the exception library can be compiled with any ANSI C compiler. However, our goal to become independent of the C++ run-time systems has not been reached yet. Looking a...
Intializes a new instance of the Exception class. Syntax C++ Exception(int32 hresult); Exception(int32 hresult, ::Platform::String^ message); Parameters hresult The error HRESULT that is represented by the exception. message A user-specified message, such as prescriptive text, that is associated...
Specifically, this base class is the root of the standard exception classes defined in<stdexcept>. The C string value returned bywhatis left unspecified by the default constructor, but may be defined by the constructors for certain derived classes as an implementation-defined C string. None of ...

exception_class和exception_cleanup是Level 2抛出exception的API设置的。Level 1 API不处理exception_class,只是把它传递给personality routine。Personality routine用该值区分native和foreign exceptions。 libc++abi __cxa_throw会设置exception_class为表示"CLNGC++\0"的uint64_t。libsupc++则使用表示"GNUCC++\0"的uin...
