关于API HOOK（OpenProcess)，根据网上文章改写

 以下是部分程序，在VC++6.0   Plat  SDK 2003 SP1下编译通过

#include <windows.h>
#include "APIHook.h"

extern CAPIHook g_OpenProcess;

// 自定义OpenProcess函数
#pragma data_seg("YCIShared")
HHOOK g_hHook = NULL;
DWORD  dwCurrentProcessId=0;
#pragma data_seg()

HANDLE  WINAPI Hook_OpenProcess(DWORD dwDesiredAccess, BOOL bInheritHandle,  DWORD dwProcessId)
{
    typedef HANDLE  (WINAPI *PFNTERMINATEPROCESS)(DWORD, BOOL,DWORD);
 
 if(dwProcessId != dwCurrentProcessId)
 {
   return ((PFNTERMINATEPROCESS)(PROC)g_OpenProcess)(dwDesiredAccess,bInheritHandle,dwProcessId);
 }
 return 0;
}

 

// 挂钩OpenProcess函数
CAPIHook g_OpenProcess("kernel32.dll", "OpenProcess",
      (PROC)Hook_OpenProcess);
