Hi Thomas, This sentence in the header file comment (which should be in the documentation but isn't) explains the problem.
> The bookmark data must have been created with the > kCFURLBookmarkCreationSuitableForBookmarkFile option. The bookmark data created by CFURLCreateBookmarkDataFromAliasRecord() won't have the kCFURLBookmarkCreationSuitableForBookmarkFile option set in it. Before CFURLCreateBookmarkDataFromAliasRecord(), Finder Alias files (bookmark files) were created by the Finder and so we needed the bookmark data in the files created by CFURLCreateBookmarkDataFromAliasRecord() to provide the same (and a little more) functionality. The kCFURLBookmarkCreationSuitableForBookmarkFile option enforces that. So, if you want to create a bookmark file from an AliasRecord, you either have to: (1) Resolve the AliasHandle to a FSRef, convert the FSRef to a CFURL, create a bookmark to the CFURL using the kCFURLBookmarkCreationSuitableForBookmarkFile option, and then write the bookmark. (2) Do what your stack overflow code does but after creating the bookmark from the AliasRecord, resolve the bookmark to its target, and then create a new bookmark to the target using the kCFURLBookmarkCreationSuitableForBookmarkFile option, and then write the bookmark. CFURLCreateBookmarkDataFromAliasRecord() was intended as a way to convert alias records stored a program's own data files to a bookmark data with no I/O. - Jim > On May 18, 2016, at 1:50 PM, Thomas Tempelmann <[email protected]> wrote: > > (This may be a bit off-topic, as this is a user-level question, but there are > the right people on this list who can answer this, I think) > > I'm trying to write bookmark files with content from Alias data generated by > the Alias Manager.
