I have the following task I need to implement.
1. I have a queue of NSData objects, usually representing a continuous stream,
but delivered in variable-sized chunks. However some chunks could be missing,

Would it help to read some of the Internet RFCs? They deal with this
kind of things in various ways.
Not that they're concerned with Objective-C or Cocoa but the concepts
might be useful.

Hi All,

comments):

Hi,
I would assume it’s because you aren’t checking the value of myBaseBufferPtr
after malloc returns. It could be nil there. So then later is the first place
you try to deref it (even though it’s now assigned to a new variable), so
that’s the first place a nil deref can be checked. You
