The following are code names used for internal development cycle iterations of the Windows core, although they are not necessarily the code names of any of the resulting releases. With some exceptions, the semester designations usually matches the Windows version number.
C does not provide direct support to exception handling: it is the programmer's responsibility to prevent errors in the first place and test return values from the functions.
Microsoft supports SEH as a programming technique at the compiler level only. MS Visual C++ compiler features three non-standard keywords: __try, __except and __finally — for this purpose. Other exception handling aspects are backed by a number of Win32 API functions, [2] for example, RaiseException to raise SEH exceptions manually.
The first hardware exception handling was found in the UNIVAC I from 1951. Arithmetic overflow executed two instructions at address 0 which could transfer control or fix up the result. [16] Software exception handling developed in the 1960s and 1970s. Exception handling was subsequently widely adopted by many programming languages from the ...
The location (in memory) of the code for handling an exception need not be located within (or even near) the region of memory where the rest of the function's code is stored. So if an exception is thrown then a performance hit – roughly comparable to a function call [24] – may occur if the necessary exception handling code needs to be ...

Exception safety is provided for stack resources (resources that are released in the same scope as they are acquired) by tying the resource to the lifetime of a stack variable (a local variable declared in a given scope): if an exception is thrown, and proper exception handling is in place, the only code that will be executed when exiting the ...
Exception safety is the state of code working correctly when exceptions are thrown. [1] To aid in ensuring exception safety, C++ standard library developers have devised a set of exception safety levels , contractual guarantees of the behavior of a data structure's operations with regards to exceptions.
