Do you use CFSocketCreateWithNative or another function that needs a pointer to callback function ?
In that case, you need to convert your CFM pointer to a Mach-O pointer before passing it.


Tak a look at the CFM_MachO_CFM sample code on Apple Developer Connection :
http://developer.apple.com/samplecode/CFM_MachO_CFM/listing1.html


The MachOFunctionPointerForCFMFunctionPointer function might be what you need.


Hope this helps. Eric

Hi Folks -

I'm facing a very strange situation. I have a CFM application which is
trying to use BSD sockets for a client/server communications (the client is
a CFM app and the Server is a Mach-O app).


I'm loading the system framework and binding the function pointers properly
and doing the correct CFM to Mach-O bridge from the Client Side (i.e. CFM).


All of the socket functions I am using are fine (i.e. execute correctly and
I'm getting the expected results), but when I call the "send" or "connect"
functions my client app (which is CFM) based crashes.


What I did was then make a Mach-O bundle which basically does a pass through
to the BSD sockets from my CFM client app. I load that Mach-O bundle from
the CFM client app and everything works.


Is there something that I can't do from the CFM side when using the BSD
sockets interface? Or am i plain wrong in my code?


Thanks & Regards -

Paul Chadha
