Dear Bartosz
First of all thank you for gpiomon software.

I try to use if for data acquisition from an optical sensor. It works fine
from command line but when I try to run it as QProcess in QT (GUI) there is
a problem with buffering. The output is transferred occasionally in large
pieces. What I need is to get output immediately after each line. I plan to
distribute my software as open source.

As I understand this problem can be solved by adding to your code 
setbuf(stdout, NULL);
or 
fflush(stdout) 
after each line.

I hope you will be able to help me with this.
Best wishes
Adam
