I have some data. I now need a generic pointer to the memory holding
the data, as well as the size of that memory block, in order to pass
the data to a function. How can I do this?

I suggest you do something like this: (warning - written in Mail, untested, use at your own risk, etc.)

NSData *data = [NSData dataWithContentsOfFile:@"/testData"];

SomeFunction([testData bytes], [testData length]);

I got that simply by glancing at the NSData documentation. NSKeyedUnarchiver is for unarchiving data that was previously archived using NSKeyedArchiver and isn't a general-purpose data- loading object.
