Hmm, after reading the other e-mails I thought there must be something I'm
missing.

So I went and added in Globals.cp

CFStringRef gSomething = CFSTR("Something");

And in Globals.h I added

extern CFStringRef gSomething;

And then in my main I added length = CFStringGetLength(gSomething); and the
result was 9.

What I am missing about declaring global CFStrings that people would go to
any more trouble that this? I had no problem at all using this outside of a
function. This has been true in both CFM and mach-o apps.

Doesn't this work?

In "globals.cp"

static CFStringRef gSomething = CFSTR("Something");

In globals.h

extern CFStringRef gSomething;

Note that a CFStringRef is implicitly const -- it's not a
CFMutableStringRef

Hi. I was wondering, is there a way to use CFSTR for a global variable

in

C? Does something like this (outside of a function):
static const CFStringRef blah = CFSTR("blah");
results in this error:
error: initializer element is not constant

Do I need to use __attribute__((constructor)) or something else, or is
there some CoreFoundation trick to use?
