Hi Gayathri,
My Server and Client application are Windows based. Also the application
is huge, so its not possible to rewrite at this time. Maybe later we can do
that, but as for now, we are looking into alternate method for this. If we
decide to revisit this issue then i will look into this.
Hi Eric.,
First of all i am a she :) and I took a maternity break off from
work..which is why I am jobless..but busy feeding and diapering my
little one :)..sure I can take up your offer, please email me at
suraj...@gmail.com.

The thing is as Eric says, you really have to rewrite ur serv

Harsh,
I would take up his offer of help. Socket control over multiple
sockets is tricky code and very specific to what you are trying to
do. My environment is single threaded and does similar things to
yours -- but as Gayathri said, there are many details and exceptions
and although with s

Thanks.
It's very easy to get things wrong and it won't work unless
Hi.,
Yes, once you make the socket noblocking, your current ssl API,s will
not work. that is why I asked you to write the asynchronous state
machine. Go thro the man pages for ssl accept, ssl read, ssl write for
non blocking cases. You need to handle special cases called want read
and write errors
Hi,
I used the following code to change the socket to non blocking, but its
still not successful, now its not even able to complete SSL_Accept. I am
changing the socket option for the accepted socket.
unsigned long iMode = 1;
int nReturn = ioctlsocket(sock, FIONBIO, &iMode);
Harsh.,
If u have any specific doubts in writing this asynchronous state
machine email me privately at suraj...@gmail.com.
I am pretty much jobless right now and can spend some time on this.
Thanks

Yes, you need to make the underlying socket non blocking, and at the
same time gotta change the way you call SSL_accept, SSL_read, write
etc to handle non block error conditions like want_read, want_write
errors, use the code Eric has given to make the fd non block, or u can
also set the bio non bl
Change the sockets. This is what I use:
int setblock(fd, mode)
int fd;
int mode; /* True - blocking, False - non blocking */
{
int flags;
int prevmode;
flags = fcntl(fd, F_GETFL, 0);
prevmode = !(flags & O_NDELAY);
if (mode)
Thanks for the reply Gayathri.
Do you mean to changing the sockets to non blocking, or when i create bio
for ssl to make that as non blocking?
Thanks.

And I cannot imagine a case where a blocking FD is useful except it
is lazier to code that way. You need to use non-blocking. E

Okay from what I can understand, if you make ur underlying fd non blocking

finished with its processing the other client will not be able to
communicate with the server as the previous fd is blocked. The server is

Gayatri,
My server code is single threaded and i am using blocking sockets, i am
using fd_set and select to wait for event on socket, and then performing
operation based on the event that acts on a socket.
I have an array of sockets to listen. So if i start listening on 3 different
ports and from m
Harshvir,

My code is all jumbled up, its a big big code. I dont think i can share the
code.
If there is some particular call that you want to see, please let me know i
will share the function call or block of calls.
Thanks.
