对绝对地址0x100000赋值 让程序跳转到绝对地址是0x100000去执行

1，要对绝对地址0x100000赋值，我们可以用

(unsigned int*)0x100000 = 1234;

2，那么要是想让程序跳转到绝对地址是0x100000去执行，应该怎么做？

*((void (*)( ))0x100000 ) ( );

首先要将0x100000强制转换成函数指针,即:

(void (*)())0x100000

然后再调用它:

*((void (*)())0x100000)();

用typedef可以看得更直观些:

typedef void(*)() voidFuncPtr;

*((voidFuncPtr)0x100000)();
