Winsock Wrapper[C++]
« on: November 11, 2005, 11:32:35 PM »
This wrapper was not written by me, but i use it. Unfortunatly i couldnt find the one i wrote myself( to much shiet on my pc) so ill share this one with you..


These are placed in a .def file, for exporting.. they are 'most' if not all the winsock functions used by the winsock dll.
Code:

This is where the hooking take place.. Wht happens is when one of these Functions are called it makes a JMP to our PRototype of the function, this also goes in a cpp file

Code:
ws2_32_hook.cpp
CODE

#include "ws2_32.h"

  break;
case DLL_PROCESS_DETACH:
  FreeLibrary( h_original );
  break;
default:
break;
}
return TRUE;
}

And this is HOW its used..Smiley

Example:
CODE

//ws2_32_hook.cpp:
int WINAPI h_connect(SOCKET s, struct sockaddr *name, int namelen)
{
int ret = plugin->ModOnConnect(s,name,namelen);
return p_connect(s,name,namelen);
}

//ws2_32.h:
extern int (__stdcall *p_connect)( int s, const void* name, int namelen);

Cheers.
