thx :)

yep, i looked over the sources and it looks very well ............
.........but there won't be a 

        int readFile(const char* fileName, int nodeNumber, int *value)

method in the libgomd at all ;) sorry.

The libgomd does not read from /proc in any case ! 
It reads from the gomd socket.
So this method has to :
-connect to the configured gomd (from config-file)
-request information (e.g. GET LOAD 1)
-the gomd will read from /proc 
 and return the read value to the socket 
-the libgomd method will get the returned load value

Even more : the libgomd must not read from /proc/hpc at all because 
/proc/hpc won't  be there on a non-openMosix system running a openMosix
monitor using libgomd. The client application later can run on any kernel, 
not only an openMosix kernel.
As discussed the only "one" which reads from /proc/hpc is the gomd (daemon)
which answers queries from the libgomd methods.

mmhmm, there is no need for /proc constants in libgomd at all as explained.

....... at least it is how i see it. Please feel free to correct me anytime.
I am open for discussion and if there should be a good reason for it ok.
Maybe we have to irc again ;)

howdy,

........ hey JP ;) i do not want to bother you at all.
Your coding is appreciated and the dyn-lib stuff is really cool already.
We just have to fixed + discuss the conceptional issues a bit more i think.
