Need opinions about questions for new design of clients handling.

Hi,

I need your opinions about questions for new design of clients handling.
I have many questions for you and I give you my opinion.

1) Do you think that a mono-threaded application is allow to create more than 
one CONTEXT 
to a identical PC/SC Daemon by SCardEstablishContext in one thread?

IMHO (In My Humble Opinion): I don't see the need.

2) Do you think that for multi-threaded application each thread must create a 
CONTEXT to the 
identical PC/SC Daemon if it wants to used it? Or do you think that a global 
context for all the 
thread is sufficient?

IMHO: I think that for each thread a CONTEXT is needed.

3) If you think as me to the previous question. Do you think that each thread 
have only the right 
to close its context and not the contexts of her sisters thread?

IHMO: yes and thus only to SCardDisconnect to the CHANNEL create in this  
CONTEXT (by 
SCardConnect).


4) Actually we have a serialisation of the requests in the scope of all 
clients. I think that we 
need a serialisation on the calls only in the scope of each thread of an 
application.


PROBLEM:
Actually for one application with 2 threads if you have put the 
--enable-threadsafe in the .
/configure only one thread is executed and the other is stopped until the 
return of the first.

GOAL: 
The goal of this new design is to have a more efficient PC/SC Resource manager 
in order to 
allow that a maximum readers dialog with a maximum card in the same time. 

I wait your feedback. Perhaps there are some problems that I have not see, or  
some goals that 
interest you or perhaps you have some ideas.

Regards,

Damien Sauveron
