Hi
I need your help on SSL_shutdown(). . The Client send "close notify" to
server first to initiates the close connection. This first call return
0 , which it is correctly. Then The Client call SSL_shutdown again to
wait for "close notify" form Server. The second SSL_shutdown call RETURN
0 , INSTEAD OF 1. I DO KNOW WHY??. PLEASE HELP.
The following Close() function to handle SSL_shutdown(). The client
send out 5 messages, then call Close() function. The Server 's SSL_read
return SSL_ERROR_ZERO_RETURN, then call Close(). The Server behaves
correctly.
AT Client side:
. Call 1 to set socket to blocking.
. Call 2, return err == 0 which it is right. ( send close notify).
. Call 3
. Call 4 (waiting for close notify from Server) with RETURN 0
INSTEAD OF 1. why ???
At Server side:
. Call 1 to set socket to blocking.
. Call 2, return err== 1, complete shutdown
. Jump to 8 which it is supposed to be.
.
Close()
{
1.setSocketToBlocking()
2. int err = SSL_shutdown()
3. If (err == 0) // not complete yet
4. { err = SSL_shutdown()
5. if (err == 1) // complete shutdown
6. {
--close all..;
}
else
{
cout << "Error" << endl;
}
7. }
8. else if (err== 1)
9. {
--close all..;
}
else if ( err < 0)
{
cout << "ERROR.." << endl;
}
}
}
Thank You.
