Thanks for the interesting and detailed replies. I realize that I have
much homework to do now but please let me address a couple of initial
concerns (spanning your collective replies).
1. I'm not clear about one aspect of NSTask: When the Moriarity example
for instance explains that NSTasks are "one-shot", does this mean that
if my model/background process is continuously receiving data from the
serial port that it can continue to send data to the controller? Or
does it mean that I will need to continue to invoke NSTasks for each
chunk of data that I want to receive into the controller and
subsequently update in an NSTextField? That must sound like a dumb
question. I just want some insight while I try to understand these
complex looking examples.
2. How do I set up a delegate in a simple C process developed outside
of IB? I've seen some examples of how to this in several O'Reilly Cocoa
books but these were all (as I recall) visually connected in IB using
an outlet attached to the controller. Would I need to be using
Objective-C constructs/messaging in my C code? Hmm... maybe I need to
spend some more time reading so this all becomes clear.
Sorry for the ignorance and nuisance...
Saul
