* http://www.codeproject.com/cpp/exceptionhandler.asp (explaining the stuff, but for VC++. Note that, on x86, VC++ and most other PC compilers use a stack-based unwinding and handling mechanism known as SEH, common to OS/2, Windows and Windows NT and described in detail in a famous MSJ article, http://www.microsoft.com/msj/0197/Exception/Exception.aspx. GCC and most other UNIX compilers, instead, use the same table-based mechanism that is the rule on RISC architectures on x86 too. Also note that any use of stack-based SEH may or may not be covered by USPTO patent #5,628,016, held by Borland International, Inc. SEH on RISC architectures is table-based, thus unaffected by the patent) |
