如此递归向上回滚栈帧直到栈帧为空或找到可以处理当前异常的catch块。 以下面的程序为例: // g++ -std=c++11 test.cc -o test.exe#include<iostream>#include<exception>#include<cstring>usingnamespacestd;structExceptionA:publicexception{ExceptionA(inta,intb):a(a),b(b){}inta,b;};structExceptionB:pu...
stack unwinding是指在抛出异常的时候会根据函数调用栈递归的向外处理这个异常, 直到遇到找到匹配的 catch 来处理这个异常, 处理完这个异常之后, 函数会调用析构函数释放申请的内存, 防止内存泄漏 Much like functions that differ only in their return values can not be overloaded, functions differing only in the...
1)用于 catch 相应的 exception,对于一个函数来说,如果该函数中有 catch 语句,且能够处理当前的异常,则该 catch 就是 landing pad。 2)如果当前函数没有 catch 或者 catch 不能处理当前 exception,则意味着异常还要从当前函数继续往上抛,因而 unwind 当前函数时有可能要进行相应的清理,此时这些清理局部变量的代码...

User-defined exceptions usually follow this pattern.[7][8][9] To avoid unnecessary copying of the exception object and object slicing, the best practice for handlers is to catch by reference.[10][11][12][13] Notes Feature-test macroValueStdFeature __cpp_constexpr_exceptions 202411L (...
