myinteger i;// is equivalent to int i;mystring s;// is the same as char *s;myfunc f;// compile equally as void (*f)(); 回调函数(Callback Function) 如果说 函数指针 是语言相关的话**,回调函数 就是一个语言无关的概念了。回调函数这个名字起的很好,可以明显
The simple answer to this first question is that a callback function isa function that is called through a function pointer.If you pass the pointer (address) of a function as an argument to another, when that pointer is used to call the function it points to it is said that a call bac...

发生函数调用的时候,主要通过call functionlabel来发生指令跳转。 call指令主要做如下两件事情: 把返回地址(当前指令的下一条指令地址)压入栈; 跳转到functionlabel 比如如下main函数调用了swap函数: 调用之前:esp寄存器存储0x108,eip执行到0x40057e 调用之后:esp寄存器存储0x104,eip执行到0x40052d,栈0x104存储了返回...
