Since exceptions in C++ are supposed to be exceptional (i.e. uncommon/rare) events, the phrase "zero-cost exceptions" [note 2] is sometimes used to describe exception handling in C++. Like runtime type identification (RTTI), exceptions might not adhere to C++'s zero-overhead principle as implementing exception handling at run-time requires a ...
C++/WinRT also ships with the cppwinrt.exe tool, which can be pointed at a Windows Runtime metadata (.winmd) file to generate a header-file-based standard C++ library that projects the APIs described in the metadata for consumption from C++/WinRT code. Windows Runtime metadata (.winmd) files provide a canonical way of describing a Windows ...
SEH on 64-bit Windows does not involve a runtime exception handler list; instead, it uses a stack unwinding table (UNWIND_INFO) interpreted by the system when an exception occurs. [4] [5] This means that the compiler does not have to generate extra code to manually perform stack unwinding and to call exception handlers appropriately. It merely ...
In computer programming, several language mechanisms exist for exception handling. The term exception is typically used to denote a data structure storing information about an exceptional condition. One mechanism to transfer control, or raise an exception, is known as a throw; the exception is said to be thrown. Execution is transferred to a catch.
windows.h is a source code header file that Microsoft provides for the development of programs that access the Windows API (WinAPI) via C language syntax. It declares the WinAPI functions, associated data types and common macros. Access to WinAPI can be enabled for a C or C++ program by including it into a source file: #include <windows.h>
C++/WinRT is an entirely standard modern C++17 language projection for Windows Runtime (WinRT) APIs, implemented as a header-file-based library, and designed to provide first-class access to the modern Windows API. With C++/WinRT, Windows Runtime APIs can be authored and consumed using any standards-compliant C++17 compiler.
Most assembly languages will have a macro instruction or an interrupt address available for the particular system to intercept events such as illegal op codes, program check, data errors, overflow, divide by zero, and other such.
The language extensions borrow syntax from C++/CLI but target the Windows Runtime Universal Windows Platform native code instead of the Common Language Runtime and managed code. It brings a set of syntax and library abstractions that project COM's WRL subset-based WinRT programming model in a way that is intuitive to C++/CLI managed extensions ...
