Hello,

I am using GNURadio with an DVB-T Stick.  
Is there a way to tell GNURadio to exit the flowgraph when an error  
occurs. For example if there occurs an error with the RTL, currently  
GNURadio outputs the error, but keeps running.

sincerly

Unfortunately, no. This is an old and known issue:  
[http://gnuradio.org/redmine/issues/528](http://gnuradio.org/redmine/issues/528)

The solution to which requires some deep surgery.
