Accessing Cocoa instance variables from C functions


  • Subject: Accessing Cocoa instance variables from C functions

I've got an Objective-C class that makes use of a C library I've written which has several callbacks. I want to implement these callbacks in my class, but I can't seem to access the class variables from these callbacks. The compiler tells me that the instance variables I'm trying to access are undeclared. Here's a snippet of my code.

void ITPhaseChange(char *message)
{
	NSLog(@"PHASE CHANGE: %s\n", message);
	[phaseText setStringValue:[NSString stringWithCString:message]];
}

Now with just the NSLog(...), everything compiles fine. But I want to work with the `phaseText' outlet from within this function. Is this possible?
