Fn FBLog() Proof of Concept

Fn FBLog() Proof of Concept
Objective-C offers the NSLog() function
which returns a formatted message
to the Apple System Log facility in the
C printf() function style when passed
format specifiers.
Since several of us are developing
in Xcode and FB side-by-side,
I feel FB would benefit from such
a function and offer the following
code as a proof of concept. ( I admit
I have no idea how to use the Apple
System Log outside of Xcode.)
A shortcoming of this code is that
it is left to the user to create
and release the resulting CFStringRef.
Also, it would be more user-friendly
as a call rather than a function to
better replicate NSLog().
Ideally, this would call the message
window on top of any windows created
within the programmer's FB code.
I am submitting this to both the FB
and the FBCocoa lists.
Comments welcome.
