Description Jan Kundrát 2011-05-23 13:57:39 UTC 
I suspect that the documentation at [1] has an error in the second code snippet, the following line:

open("/.kde/myconfig", O_WRONLY|O_TRUNC|O_CREAT);

Instead of reading the configuration from source and only then writing the second one, the original file is truncated before reading from it.

I suspect it should be changed to *read* from that file.

Thanks for pointing this out, Jan. I've changed 'open' to 'read' in the second sample config file ready for the 6.3 version of the guide.
