Re: mmap quiet failure - all reads are 0x00

Perhaps it is a bug unrelated to mmap, that screws up some of your state, then later it causes the mmap to fail. Or perhaps the mmap succeeds, but the bytes your are reading are coming from some other place. There are many debugging techniques, such as using assertions, guard malloc etc. But don

Re: Question about Archives and Serialisations Programming Guide

Sure. That would be nice. I also recall some classes for archiving and dearchiving that use introspection that automatically handle the proper action in one line of code. For simple cases with straightforward collection classes, this is a really really really nice approach and frees us from ha

mmap quiet failure - all reads are 0x00

I have image data that is stored in a 150mb file which I use mmap to read. The image data is pulled into a NSBitmapImageRep pixel by pixel and eventually shows on the screen. Only a subset of the pixel in the mmap file are pulled into a single NSBitmapImageRep. A few customers (and I have seen it

Hi Alex, Found it! Well, Jean-Daniel did - Thanks again! I was barking up the wrong tree thinking it was the back links that were the problem. Using weak caused them to (correctly as it turned out) be set to nil when the node it reference is released. The problem was in the initWithCoder metho
