[vdr] how detect vdr has closed socket in c++?

[Guido Fiala <gfiala@s.netic.de>]

As to allow to set a small SVDRP-timeout without kvdr loosing a command - how 
to detect if vdr has closed the socket?

I tried to check errno after calling write(), but this helps just after the 
second write()-operation on the socket and then it's too late.
Some other way i missed?

I ask, because many programs like to use SVDRP at once and i like to make kvdr 
intelligent enough to reconnect silently and fast without loosing an action.
