Exception Handling In ANSI CGregory Colvin
c出错处理Exceptionhandling 本节介绍的出错处理是ANSI-C++标准引入的新功能。如果你使用的C++ 编译器不兼容这个标准,则你可能无法使用这些功能。 在编程过程中,很多时候我们是无法确定一段代码是否总是能够正常工作 的,或者因为程序访问了并不存在的资源,或者由于一些变量超出了预期的范 ...
至少不会导致因为没有处理的exception而teminate了当前程序,而如果要写出高质量高稳定性的C++代码,不掌握exception handling的技巧性使用应该是很难的(至少我是这么认为的),当然了,C阵营中错误代码或返回状态信息是另一类exception技能了。
因此,Itanium C++ ABI: Exception Handling分成Level 1 Base ABI and Level 2 C++ ABI两部分。Base ABI描述了语言无关的stack unwinding部分,定义了_Unwind_*API。常见实现是: libgcc:libgcc_s.so.1andlibgcc_eh.a 多个名称为libunwind的库(libunwind.so或libunwind.a)。使用Clang的话可以用--rtlib=compiler-rt...
The basic function of exception handling is to transfer control to an exception-handler when an error occurs, where the handler resides somewhere higher up in the current function call hierarchy. Standard C has a mechanism to accomplish this:setjmp()andlongjmp(). Example 1 shows a simple impleme...
Handling Errors Exceptionally Well in C++By Alex Allain One benefit of C++ over C is its exception handling system. An exception is a situation in which a program has an unexpected circumstance that the section of code containing the problem is not explicitly designed to handle. In C++, ...

While structured exception handling works in C++ programs, you can ensure that your code is more portable by using C++ exception handling. The C++ exception handling mechanism is more flexible, in that it can handle exceptions of any type. C exceptions are always of type unsigned int. Using ...

对于ELAB来说,Exception Handling Policy = Exception Type + Exception Handler(s) ,也就是说异常处理策略规定了对于某种类型的类型需要通过那些Exception Handler去处理。 从这种意义上讲,ELAB的异常处理机制是基于Exception Type的,异常的类型是我们处理异常的最小粒度。对于一个确定的异常处理策略,在不同场合抛出的...
