The previous blog post simply introduces the process of C + + exception handling, but in some detail the area over, for example, _unwind_raiseexception is how to reconstruct the function site, personality routine is how to clean up the stack of

Prot Otype mode mainly solves the problem of shallow copy and deep copy, but generally not too bad programmer can avoid this kind of mistake. Personally think it contains a lifetime of two, two four of Taiji thought,But how is it implemented in C,

Program design: The cat shouted, all the mice began to flee, the master was awakened. (C # language)Requirements:1. To have linkage, the behavior of the mouse and the host is passive.2. Considering extensibility, cat calls can cause other linkage
