------------------------------------
Chuck, you and I have both been around the block enough times to know that
without the warnings constantly annoying people, the problems will never get
fixed.
> Mismatch uint32_t / size_t generates many compile warnings, esp in 64-bit

> Key: QPID-2574
> URL: https://issues.apache.org/jira/browse/QPID-2574
> Project: Qpid
> Issue Type: Bug
> Components: C++ Broker, C++ Client, Code Generator
> Affects Versions: 0.6
> Reporter: Steve Huston
> Priority: Minor
>
> There are many places in the C++ code that mix uint32_t, usually in the form
> of an encoding or Buffer size, with size_t, usually the result of a size()
> call to a string or some other container. In a Windows 64-bit build this
> produces a warning for each occurrence similar to:
> 3>C:\ace\exported\qpid\trunk\qpid\cpp\src\qpid/broker/Exchange.h(122) :
> warning C4267: 'return' : conversion from 'size_t' to 'uint32_t', possible
> loss of data
> This type of code is present in both hand-written and generated code, which
> is why I included the Code generator in the Components.
> Some can be removed with a cast - for example, the Uuid::encodedSize method
> isn't going to return a value greater than 2^32-1, so it can be safely cast
> away. But the problem should be dealt with more cleanly, I think.
