You can get info about the current application by calling SysCurAppDatabase
to get a reference to the application database, then using the normal DB
manipulation functions exposed by the Database Manger (DmDatabaseInfo being
one of the more useful).

I'm not sure exactly how it does it, but I would guess that it sums up the
record count for all non-resource databases with the same creator ID. I
don't know of a way to hide records from that count.

This couldn't be done by a macro, since the preprocessor doesn't understand
C++. With CW Palm 7, you can use the predefined identifiers "__func__"
which is a constant string with the name of the currently compiling
function. Both CWP7 and GCC allow you to use __FUNC__ and __PRETTY_FUNC__
for similar tasks.
