XSetIOErrorHandler

[Albert Sanchez]

At the beggining of my program I check wether there is connection with the
display with the XOpenDisplay function. This works fine. The problem is when
later I lose the connection (desconnecting the network cable) and my
function specified with XSetIOErrorHandler is not called. Do you know what
could be the problem? Is there any alternative to check the disconnection of
the display?

Thanks!
Albert
