Hi,
I'm trying to create a client application that needs to read and write data from a socket. What I want to do is to have one thread reading the socket and another thread writing to the same socket, but I can't get it to work.
I know that there is a problem with having two threads reading from the same Handle (as in the aaaa bbbb example), due to the locking. To avoid this blocking I open the socket with Network.Socket.socket and create two handles with socketToHandle, one in ReadMode and one in WriteMode.
But the threads still seem to be blocking each other and the program runs very slowly. I am using channels to have the read and write threads communicate with other threads in the application and by removing a writeChan in one of these other threads the program crashes with a "Fail: thread blocked indefinitely".
Are there any good examples of how to use sockets with Haskell. I have no way of knowing in which order I will need to read data from and write data to the socket.
I am using ghc version 6.2.2 on Linux.
Thanks in advance -Mårten- _______________________________________________ Glasgow-haskell-users mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/glasgow-haskell-users
