Yes, I already did this. But I am asking because of other files. There must be alot of outdated files. I don't think the purpose of CVS is to update each file manually.

There can be several causes for this: 1) You have created the file locally, and someone else added a file of the same name to CVS. 2) Your sandbox has become corrupted (possibly due to interference from antivirus programs). To solve the problem: Rename or delete the affected files, then perform a CVS Update. " I didn't change/modify/create any new files in the directory of TinyOS2.x I tried to rename the the file where the update stopped but with no use. I am using TortoiseCVS on WindowsXP.

In the function updateNeighborEntryIdx the following if statement calls the function updateNeighborTableEst if (NeighborTable[idx].rcvcnt >= BLQ_PKT_WINDOW) { updateNeighborTableEst(NeighborTable[idx].ll_addr); } Inside the updateNeighborTableEst function we have the statements minPkt = BLQ_PKT_WINDOW; totalPkt = ne->rcvcnt + ne->failcnt; then we have the condition if (totalPkt < minPkt) { totalPkt = minPkt; //statement 1 } which will never be satisfied because, at least, rcvcnt = BLQ_PKT_WINDOW (from the if in updateNeighborEntryIdx) . So, always total >= BLQ_PKT_WINDOW 'minPkt' The second statement is right after statement 1 in updateNeighborTableEst if (totalPkt == 0) { ne->inquality = (ALPHA * ne->inquality) / 10; //statement 2 } This statement is never satisfied because statement 1 always set totalPkt > 0. Another main reason for not satisfying this statment, updateNeighborTableEst will never be called if rcvcnt < BLQ_PKT_WINDOW which means totalPkt > 0 (remember totalPkt = ne->rcvcnt + ne->failcnt). I searched the code for other calls to updateNeighborTableEst but I didn't find any. I'd appreciate it if someone can highlight the importance of these 2 statements.
