In fact, in your case, what you do is just reading from the socket in a thread. The data is taken from the socket. Then the other do another read and there's no data. If you want the data to be received by the two processes, you should share it (threads have the same adress space, it's easy to do without any mechanism). In your case, if 2 threads want the data received (let's say thread A and thread B), you should do 3 threads : the first thread which just reads from the socket. When data is received, it wakes up threads A and B. -- tyler tyler@xxxxxxxx ___________________________________________________________________________ Faites de Yahoo! votre page d'accueil sur le web pour retrouver directement vos services préférés : vérifiez vos nouveaux mails, lancez vos recherches et suivez l'actualité en temps réel.
