C++获取寄存器eip的值

程序中需要打印当前代码段位置 如下

 #include <stdio.h>
 #include <stdlib.h>
 #include <math.h>
 #ifdef WIN32
 #include <windows.h>
 #endif
 typedef void (*pFunGetip)(int n);
 void getip(int n);
 void __declspec(naked) fun()
 {
 __asm {
   mov eax,[esp];
   ret;
 }
 }
 int main()
 {
     printf("main=0x%p\n",main);
     void* p=;
     __asm {
         lea edi,p
         call fun
         mov [edi],eax
     }
     printf("p=0x%x\n",p);
 #ifdef WIN32
     system("pause");
 #endif
     return ;
 }

来个纯C++的函数

 static unsigned char* getEIP()
 {
   unsigned int n=;
   unsigned int* p=&n;
   unsigned int* p2=(unsigned int*)getEIP;
   unsigned int m=(((unsigned int)p2)&0xfff00000);
   unsigned int m2=m+0xfffff;
   for(int i=;i<0xff;++i)
   {
       if(m&p[i])
       {
           if(p[i]<m2)
           {
               return (unsigned char*)p[i];
           }
       }
   }
   return ;
 }
