“dangerwillrobinsondanger” correctly points to Core Foundation. I’m embarrassed to have forgotten — it should be very helpful to you, assuming it mixes with AVFoundation. > On 7 Sep 2016, at 11:33 AM, じょいすじょん > wrote: > > Have you considered Core

Have you considered Core Foundation? https://developer.apple.com/library/ios/documentation/CoreFoundation/Reference/CFNotificationCenterRef/ It is all C Another alternative is to look at the Objective-C runtime library routines. You can do a lot with the language from C... > On 2016 Sep 8, at

C callbacks with NSNotificationCenter?

As a C programmer I'm trying to avoid Objective C whenever and wherever possible. The good thing is that I can do most interaction with Cocoa from normal C functions. I only had to write very few classes. Most of the Cocoa stuff can be done from normal C functions just fine. Now I'd like to
