Sorry, but I don't understand. Let's see for example UdpSocket class.
The only point in the CUdpSocket.c code in which I assign a call-back is
this:
-----------------------------------------------------
void CUdpSocket_AssignCallBack(long t_obj,int t_sock)
{
...
GB.Watch (t_sock , GB_WATCH_WRITE,(void*)CUdpSocket_CallBack,0);
...
}
-----------------------------------------------------
The fourth parameter is zero, and in the callback function :
-------------------------------------
void CUdpSocket_CallBack(long lParam)
{
....
}
-------------------------------------
I receive the socket descriptor in lParam.
Now I've changed the fourth parameter:
---------------------------------------
void CUdpSocket_AssignCallBack(long t_obj,int t_sock)
{
...
GB.Watch (t_sock , GB_WATCH_WRITE,(void*)CUdpSocket_CallBack,t_obj);
...
}
---------------------------------------
(t_obj is a pointer to a CUDPSOCKET structure)
And it still works! I receive the socket descriptor in lParam!
I'm puzzle... What I'm doing wrong?
