the apr_ namespace is unavailable, except to a select few files in the
core. Modules can not use the apr_ namespace. The one exception to
this is mod_openmrcp, where it gets access to the apr_namespace via the
openmrcp libraries, as apr is used natively in that library. Further, in
the core, we should only be using the apr_ namespace for those functions that
we have chosen not to wrap and expose out of the core. The reasons for
this are, more or less as stated. We have already had several occasions
where we have used the wrapper functions to correct bugs in apr, or to modify
the behavior of functions, as we recently did with some of the socket code. <br>

I tend to agree, at least from the standpoint of a non-coder who wants<br>
(or needs) to read the source code.<br>

I can't either. To preserve modularity, and to make it easier to<br>
migrate away from apr if that need should arise, a clean and consistent<br>
namespace seems appropriate.<br>

<br>
Sounds good. I'm studying up on apr (and thusly switch_xxx) and
if/when<br>
I'm comfortable submitting patches I will most definitely do so.<br>
