Hopefully this is not OT. If so, my apologies (which list would be appropriate then?). I have to implement a shared library (within a framework). The bottom edge of the shared library will communicate with a daemon via local sockets (the CFLocalServer was a helpful starter). However, I will be required to notify the client of the shared library of interesting events (changes in hardware, departure of hardware, etc). Within Windows, I might have used custom messages to be send to a window procedure. However, I'm not sure at all what would be the best way to proceed here with OSX. The simplest thing would be for the client of the shared library to send a callback function, which I could invoke. But that's a bit bare bones, and so I'm also looking into adding a custom source to a runloop, which would result in a callback function being invoked. I'm just not sure which way would be best for my needs. It seems that CFMessagePort would serve, but there is also CFMachPort, and I don't know which is preferable. Concerning CFMachPort, there is no CF interface for sending data to a port- the CFMachPort doc says "To send data, you must use the Mach APIs with the native Mach port, which is not described here." So where can I find this documentation? I might cringe a bit if I should be forced to use native mach APIs, because I'm not sure they would remain unchanged across OS upgrades (perhaps this is an unreasonable fear, but I'm fairly new to OSX). Any thoughts? Are mach ports the way to go for this functionality, and, if so, where might I find some mach API documentation for sending to a port? If mach ports are not the way to go, what would be? (CFMessagePort for example). I would like to stick to CF types, as I don't know right now what type of application will be using the shared library (I understand that CF types can be used by Carbon and Cocoa). thanks for any insight, Philip Lukidis _______________________________________________ Do not post admin requests to the list.
