Hi Jonathon
I'm not sure what you mean here; can you give an example of an
initialize/terminate routine?
intialize and terminate routines are the constructors and
desctructors that
get called up when a framework is loaded and unloaded
There is no such functionality. I hardly can imagine any reason why
there should be such stuff, either.
Constructors and destructors of classes should work as expected, in
case you use C++.

My application runs as a deamon that loads the framework.
If you link or weak link against a framework, dyld will do that for
you. No need to duplicate what already works.
But the issue was that when my deamon starts, it loads the
framework, but as
soon as the its parent process get kills, the framework gets unloaded.
What makes you think this is true?
If you link your app against a framework or load this framework
dynamically later, this framework will be mapped into your app's
address space. If the parent process does the same, the parent
process gets it's own copy.
If you fork a child, the child gets it's own copy of what the parent
has. If the parent terminates later, this doesn't affect the child
(short of zombie issues).
Is it the correct way ?
I think it would be a good idea to build plain applications, possibly
starting with one of Xcode's templates. In general, one doesn't have
to think much about loading/linking issues. This stuff just works as
is and changing the way it works is asking for trouble.
