// Wraps the removexattr system call, allowing an AppKit-style NSString* to
|
|
// be used for the pathname argument. Note that the order of the arguments
|
|
// has changed from what removexattr accepts, so that code reads more
|
|
// naturally.
|
|
//
|
|
// removexattr is only available on Mac OS X 10.4 ("Tiger") and later. If
|
|
// built with an SDK that includes removexattr, this method will link against
|
|
// removexattr directly. When using earlier SDKs, this method will dynamically
|
|
// look up the removexattr symbol at runtime. If the symbol is not present,
|
|
// as will be the case when running on 10.3, this method returns -1 and sets
|
|
// errno to ENOSYS.

// Removes the directory tree rooted at |root| from the file quarantine.
|
|
// The quarantine was introduced on Mac OS X 10.5 and is described at:
|
|
//
|
|
// http://developer.apple.com/releasenotes/Carbon/RN-LaunchServices/index.html
|
|
#//apple_ref/doc/uid/TP40001369-DontLinkElementID_2
|
|
//
|
|
// If |root| is not a directory, then it alone is removed from the quarantine.
|
|
// Symbolic links, including |root| if it is a symbolic link, will not be
|
|
// traversed.
|
|
//
|
|
// Ordinarily, the quarantine is managed by calling LSSetItemAttribute
|
|
// to set the kLSItemQuarantineProperties attribute to a dictionary specifying
|
|
// the quarantine properties to be applied. However, it does not appear to be
|
|
// possible to remove an item from the quarantine directly through any public
|
|
// Launch Services calls. Instead, this method takes advantage of the fact
|
|
// that the quarantine is implemented in part by setting an extended attribute,
|
|
// "com.apple.quarantine", on affected files. Removing this attribute is
|
|
// sufficient to remove files from the quarantine.
