Oh well, you can also do things in assembly of course
that's even more low level as non-ms is offering.
I prefer highlevel things which are fast!
But see my previous post to bob what i want. I have 2 possible
event which are set in shared memory:
a) go search
b) quit
for a special linux implementation i can modify that to a gosearch
command always to then quit when getting out of the loop.
No big probs to do that. So basically 1 event is what i can rewrite it
to.
How to rewrite in linux next thing:
for( ;; ) {
sleep(100);
if( sharedtree->gosearch )
break;
}
if( sharedtree->quitprogram )
..
No problems here to rewrite it to this. Just want it solved for linux!
Best regards,
Vincent
