I am calling AudioConverterNew in osstatus error 1712 the documentation under Returns: it says "returns a status code" ... really... so far, through playing around with the parameters I have only been able to get two different errors neither of which are listed at the bottom of the Audio Converter reference. they are 'mrep' and '?tmf' (casting the OSStatus to a char array) but the specific codes aren't really the point. as far as I can tell, random error codes are defined in random files, so you can't just search
What Is Osstatus Error
one file, I can't find a help document that just lets you search for an error code to get more info, and from what I can tell, in OSX you can use GetMacOSStatusErrorString() to convert an error to something useful, but there is no iphone equivalent? any help would be greatly appreciated. EDIT: ok, so casting them gives them in reverse (something I checked for 'mrep' but was not there either way round) , fmt? is in the list for the Audio Converter api, and is pretty self explanatory if a bit vague, but fair enough, still 'perm' isn't there (although it might be something to do with the simulator not supporting aac decoding) and my general question still stands. ios osx cocoa-touch cocoa error-handling share|improve this question edited Jun 21 '12 at 11:21 tomk 1,0871813 asked Feb 4 '10 at 1:55 matt 2,06421837 Apple Docs –Juan Pablo Boero Alvarez May 4 at 20:35 @matt Have you found a solution in swift ?

Some OSStatus are four-character-codes, so you can use (extracted from iPhone SDK's sample code "CAXException.h") static char *FormatError(char *str, OSStatus error) { // see if it appears to be a 4-char-code *(UInt32 *)(str + 1) = CFSwapInt32HostToBig(error); if (isprint(str[1]) && isprint(str[2]) && isprint(str[3]) && isprint(str[4])) { str[0] = str[5] = '\''; s
various Security Framework routines I have noticed return values that are not explicitly documented by the Security https://developer.apple.com/library/content/qa/qa1499/_index.html API. What do these error values mean? A: When calling various Security Framework routines I have noticed return values that are not explicitly documented by https://codedump.io/share/THrYVJGAYYDp/1/how-do-you-convert-an-iphone-osstatus-code-to-something-useful the Security API. What do these error values mean?The Security framework can return an error from three distinct categories:An OSStatus error, e.g., errSecNoSuchKeychain (-25294).A UNIX osstatus error errno-style error code + 100000, e.g., EINVAL (22) + 100000.An error from Common Security Services Manager (CSSM), one of the technologies that underlies the Security framework, e.g., CSSM_ADDIN_AUTHENTICATE_FAILED (0x8001011c).General OSStatus-style error codes can be found in MacErrors.h. Security related OSStatus-style error codes are defined in various headers within the Security framework: osstatus error codes SecBase.h, AuthSession.h, SecureTransport.h, and Authorization.h.All errno-style error codes are listed in /usr/include/sys/errno.h.CSSM errors are listed in cssmerr.h. In addition, you can get a human readable form of CSSM errors using cssmPerror, provided by the Security framework, in order to translate a received CSSM error value into its canonical name. Below is an example call within a gdb session:(gdb) call (void)cssmPerror(0, 0x8001011c) error: CSSM_ADDIN_AUTHENTICATE_FAILED (gdb) call (void)cssmPerror(0, 2147549468) error: CSSM_ADDIN_AUTHENTICATE_FAILEDNote:The Security framework adds 100000 to errno-style error codes so that the returned values will not collide with existing OSStatus values.Document Revision HistoryDateNotes2006-11-16New document that explains how to interpret errors returned by the Security Framework with an overview of Security error handling.
