写个较通用的32位apihook函数 免得每次都重写

typedef int(__stdcall *send_)(SOCKET , const char* , int , int );typedef int(__stdcall *recv_)(SOCKET, const char*, int, int);int __stdcall fake_send(SOCKET s, const char* buf, int len, int flags){return old_send(s, buf, len, flags);}int __stdcall fake_recv(SOCKET s, const char* buf, int len, int flags){int r = old_recv(s, buf, len, flags);return r;}void* hook_x86(const char* dll,const char* func,void* fake_addr){HINSTANCE hInst = ::GetModuleHandleA(dll);if (hInst == NULL)hInst = LoadLibraryA(dll);if (hInst == NULL)return NULL;char* p = (char*)::GetProcAddress(hInst, func);void* old = (void*)(p + 1);DWORD Old = 0;VirtualProtect(p - 10, 20, PAGE_EXECUTE_READWRITE, &Old);*p++ = 0xEB;*p = 0xF9;p -= 6;*p = 0xE9;DWORD* t = (DWORD*)++p;DWORD ta = (DWORD)fake_addr - ((DWORD)t - 1) - 5;*t = ta;VirtualProtect(p - 10, 20, Old, &Old);return old;}old_send = (send_)hook_x86("ws2_32.dll", "send", fake_send);old_recv = (recv_)hook_x86("ws2_32.dll", "recv", fake_recv);
