But what code? Why is it "OSStatus"? ios objective-c osx share|improve this question asked Jan 11 '14 at 16:20 user2553675 135111 add a comment| 2 Answers 2 active oldest votes up vote 10 down vote accepted As you've said, it's the result code of the function. Hovewer, http://stackoverflow.com/questions/21064696/what-is-osstatus different functions have different result codes that you can handle as you wish. for example, for Audio services, the current OSStatus codes are give in the documentation as: So as you call your functions, you check the returnes OSStatus and if it's noErr (which is what 0 is), then you can continue with your next call, otherwise you handle the error accordingly. share|improve this answer edited Jan 11 '14 at 17:18 Tommy 82.2k10129149 answered Jan 11 '14 at 16:29 Abizern 77.7k19155213 1 Thanks, I've found it too) –user2553675 Jan 11 '14 at 16:33 add a comment| up vote 3 down vote Abizern is right, nothing can replace the documentation. But sometimes the OSStatus are not clear enough, so you still can check this kind of website to have quick information http://www.osstatus.com/. share|improve this answer answered Sep 29 '15 at 7:08 Kévin Renella 570313 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password Post as a guest Name Email Post as a guest Name Email discard By posting your answer, you agree to the privacy policy and terms of service.

NSError objects to convey information about runtime errors that users need to be informed about. In most cases, a program https://developer.apple.com/library/content/documentation/Cocoa/Conceptual/ErrorHandlingCocoa/ErrorObjectsDomains/ErrorObjectsDomains.html displays this error information in a dialog or sheet. But it http://www.cocoabuilder.com/archive/cocoa/241144-how-do-track-down-an-osstatus-error-code.html may also interpret the information and either ask the user to attempt to recover from the error or attempt to correct the error on its own. The core attributes of an NSError object—or, simply, an error object—are an error domain, a domain-specific error code, osstatus error and a “user info” dictionary containing objects related to the error, most significantly description and recovery strings. This chapter explains the reason for error objects, describes their attributes, and discusses how you use them in Cocoa code.Why Have Error Objects?Because they are objects, instances of the NSError class have several advantages over simple osstatus error codes error codes and error strings. They encapsulate several pieces of error information at once, including localized error strings of various kinds. NSError objects can also be archived and copied, and they can be passed around in an application and modified. And although NSError is not an abstract class (and thus can be used directly) you can extend the NSError class through subclassing.Because of the notion of layered error domains, NSError objects can embed errors from underlying subsystems and thus provide more detailed and nuanced information about an error. Error objects also provide a mechanism for error recovery by holding a reference to an object designated as the recovery attempter for the error.Error DomainsFor largely historical reasons, errors codes in OS X are segregated into domains. For example, Carbon error codes, which are typed as OSStatus, have their origin in versions of the Macintosh operating system predating OS X. On the other hand, POSIX error codes derive from the various POSIX-conforming “flavors” of UNIX, such as
