I've modified the Objective-C API to support the position argument for
setExtendedAttribute and valueOfExtendedAttribute. The new versions
that your delegate should implement look like:
- (NSData *)valueOfExtendedAttribute:(NSString *)name
ofItemAtPath:(NSString *)path
position:(off_t)position
error:(NSError **)error;
- (BOOL)setExtendedAttribute:(NSString *)name
ofItemAtPath:(NSString *)path
value:(NSData *)value
position:(off_t)position
options:(int)options
error:(NSError **)error;
Please also note the argument name change from flags to options.
GMUserFileSystem will prefer these new selectors if your delegate
implements them. Otherwise it will call the old selector for now.
Eventually I'll probably remove support for the calling the deprecated
selectors.
I've also updated LoopbackFS and confirmed that I can copy in a file
with a ResourceFork that is larger than 128K. You can look at the
head of the source tree to see the updated API and how it is used.
