Hi
   thanks for replying quickly


 What do you mean by separate display  connections ?
 The case is this :

I mean a display connection returned by XOpenDisplay.
Thanks

   u have given a good suggestion but I dont understand if the
 pausing thread block any other thread trying to use the
Xlib with the same display connection then why it is working
 fine sometimes .
 Thanks

 that's life debugging and problems with threads. mostly you might be lucky
 and
 the threads don't clash and it HAPPENS to work - by sheer luck. when they
 do
 clash you end up with these weird problems that happen sometimes - ie
 concurrency/locking issues.

  Separate threads either need to use separate display
  connections or you need to enable thread mutexes for a shared
  connection (XInitThreads will enable Xlib's internal mutexes).
  Note still, that pausing a thread while it's in Xlib can block
  any other threads also trying to use Xlib with the same display
  connection.  You'd want to use separate display connections
  for that.
 
 Mark.

Right.  I think what Carsten is saying is, if you might need to pause a
thread in the middle of Xlib, then that thread needs to make its own
call to XOpenDisplay, so that it has its own connection, separate from
the rest of the application.
