{
All URLs can be broken into two pieces - the scheme (preceding the
first colon) and the resource specifier (following the first colon).
Most URLs are also "standard" URLs conforming to RFC 1808 (available
from www.w3c.org).  This category includes URLs of the file, http,
https, and ftp schemes, to name a few.  Standard URLs start the
resource specifier with two slashes ("//"), and can be broken into
four distinct pieces - the scheme, the net location, the path, and
further resource specifiers (typically an optional parameter, query,
and/or fragment).  The net location appears immediately following
the two slashes and goes up to the next slash; it's format is
scheme-specific, but is usually composed of some or all of a username,
password, host name, and port.  The path is a series of path components
separated by slashes; if the net location is present, the path always
begins with a slash.  Standard URLs can be relative to another URL,
in which case at least the scheme and possibly other pieces as well
come from the base URL (see RFC 1808 for precise details when resolving
a relative URL against its base).  The full URL is therefore

<scheme> "://" <net location> <path, always starting with slash> <add'l resource specifiers>

If a given CFURL can be decomposed (that is, conforms to RFC 1808), you
can ask for each of the four basic pieces (scheme, net location, path,
and resource specifer) separately, as well as for its base URL.  The
basic pieces are returned with any percent escape sequences still in
place (although note that the scheme may not legally include any
percent escapes); this is to allow the caller to distinguish between
percent sequences that may have syntactic meaning if replaced by the
character being escaped (for instance, a '/' in a path component).
Since only the individual schemes know which characters are
syntactically significant, CFURL cannot safely replace any percent
escape sequences.  However, you can use
CFURLCreateStringByReplacingPercentEscapes() to create a new string with
the percent escapes removed; see below.

If a given CFURL can not be decomposed, you can ask for its scheme and its
resource specifier; asking it for its net location or path will return NULL.

To get more refined information about the components of a decomposable
CFURL, you may ask for more specific pieces of the URL, expressed with
the percent escapes removed.  The available functions are CFURLCopyHostName(),
CFURLGetPortNumber() (returns an Int32), CFURLCopyUserName(),
CFURLCopyPassword(), CFURLCopyQuery(), CFURLCopyParameters(), and
CFURLCopyFragment().  Because the parameters, query, and fragment of an
URL may contain scheme-specific syntaxes, these methods take a second
argument, giving a list of characters which should NOT be replaced if
percent escaped.  For instance, the ftp parameter syntax gives simple
key-value pairs as "<key>=<value>;"  Clearly if a key or value includes
either '=' or ';', it must be escaped to avoid corrupting the meaning of
the parameters, so the caller may request the parameter string as

CFStringRef myParams = CFURLCopyParameters(ftpURL, CFSTR("=;%"));

requesting that all percent escape sequences be replaced by the represented
characters, except for escaped '=', '%' or ';' characters.  Pass the empty
string (CFSTR("")) to request that all percent escapes be replaced, or NULL
to request that none be.

    Returns a new file reference URL that refers to the same resource as a specified URL.

    Parameters
        allocator
            The memory allocator for creating the new URL.
        url
            The file URL specifying the resource.
        error
            On output when the result is NULL, the error that occurred. This parameter is optional; if you do not wish the error returned, pass NULL here. The caller is responsible for releasing a valid output error.

    Return Value
        The new file reference URL, or NULL if an error occurs.

    Discussion
        File reference URLs use a URL path syntax that identifies a file system object by reference, not by path. This form of file URL remains valid when the file system path of the URL’s underlying resource changes. An error will occur if the url parameter is not a file URL. File reference URLs cannot be created to file system objects which do not exist or are not reachable. In some areas of the file system hierarchy, file reference URLs cannot be generated to the leaf node of the URL path. A file reference URL's path should never be persistently stored because is not valid across system restarts, and across remounts of volumes -- if you want to create a persistent reference to a file system object, use a bookmark (see CFURLCreateBookmarkData). If this function returns NULL, the optional error is populated. This function is currently applicable only to URLs for file system resources.

            The memory allocator for creating the new URL.
        url

    Return Value
        The new file path URL, or NULL if an error occurs.

    Discussion
        File path URLs use a file system style path. An error will occur if the url parameter is not a file URL.

{ Resource access

    The behavior of resource value caching is slightly different between the NSURL and CFURL API.

    When the NSURL methods which get, set, or use cached resource values are used from the main thread, resource values cached by the URL (except those added as temporary properties) are invalidated the next time the main thread's run loop runs.

    The CFURL functions do not automatically clear any resource values cached by the URL. The client has complete control over the cache lifetime. If you are using CFURL API, you must use CFURLClearResourcePropertyCacheForKey or CFURLClearResourcePropertyCache to clear cached resource values.
 }


{
    CFURLCopyResourcePropertyForKey
    
    Returns the resource value identified by a given resource key.

    Parameters
        url
            The URL specifying the resource.
        key
            The resource key that identifies the resource property.
        propertyValueTypeRefPtr
            On output when the result is true, the resource value or NULL.
        error
            On output when the result is false, the error that occurred. This parameter is optional; if you do not wish the error returned, pass NULL here. The caller is responsible for releasing a valid output error.

    Return Value
        true if propertyValueTypeRefPtr is successfully populated; false if an error occurs.

    Discussion
        CFURLCopyResourcePropertyForKey first checks if the URL object already caches the resource value. If so, it returns the cached resource value to the caller. If not, then CFURLCopyResourcePropertyForKey synchronously obtains the resource value from the backing store, adds the resource value to the URL object's cache, and returns the resource value to the caller. The type of the resource value varies by resource property (see resource key definitions). If this function returns true and propertyValueTypeRefPtr is populated with NULL, it means the resource property is not available for the specified resource and no errors occurred when determining the resource property was not available. If this function returns false, the optional error is populated. This function is currently applicable only to URLs for file system resources.

        keys
            An array of resource keys that identify the resource properties.

    Return Value
        A dictionary of resource values indexed by resource key; NULL if an error occurs.

    Discussion
        CFURLCopyResourcePropertiesForKeys first checks if the URL object already caches the resource values. If so, it returns the cached resource values to the caller.

            The URL specifying the resource.
        key
            The resource key that identifies the resource property.

    Discussion
        CFURLSetResourcePropertyForKey writes the new resource value out to the backing store.

    Discussion
        CFURLSetResourcePropertiesForKeys writes the new resource values out to the backing store. Attempts to set read-only resource properties or to set resource properties not supported by the resource are ignored and are not considered errors. If an error occurs after some resource properties have been successfully changed, the userInfo dictionary in the returned error contains an array of resource keys that were not set with the key kCFURLKeysOfUnsetValuesKey. The order in which the resource values are set is not defined.

        key
            The resource key that identifies the resource property.

    Discussion
        Discarding a cached resource value may discard other cached resource values, because some resource values are cached as a set of values and because some resource values depend on other resource values (temporary properties have no dependencies).

            The URL object.
        key
            The resource key that identifies the temporary resource property.
        propertyValue
            The resource value.

    Discussion
        Temporary properties are for client use. Temporary properties exist only in memory and are never written to the resource's backing store. Once set, a temporary value can be copied from the URL object with CFURLCopyResourcePropertyForKey and CFURLCopyResourcePropertiesForKeys. To remove a temporary value from the URL object, use CFURLClearResourcePropertyCacheForKey. Temporary values must be valid Core Foundation types, and will be retained by CFURLSetTemporaryResourcePropertyForKey. Care should be taken to ensure the key that identifies a temporary resource property is unique and does not conflict with system defined keys (using reverse domain name notation in your temporary resource property keys is recommended).

            The URL object.
        error
            On output when the result is false, the error that occurred. This parameter is optional; if you do not wish the error returned, pass NULL here. The caller is responsible for releasing a valid output error.

    Return Value
        true if the resource is reachable; otherwise, false.

    Discussion
        CFURLResourceIsReachable synchronously checks if the resource's backing store is reachable. Checking reachability is appropriate when making decisions that do not require other immediate operations on the resource, e.g. periodic maintenance of UI state that depends on the existence of a specific document. When performing operations such as opening a file or copying resource properties, it is more efficient to simply try the operation and handle failures. This function is currently applicable only to URLs for file system resources. If this function returns false, the optional error is populated. For other URL types, false is returned.

			will be created with the same name as the bookmarked item and a ".alias" extension.  If fileURL is a url for a file and it exists it will be overwritten.  If a
			.alias extension is not present it will be added.  In addition to the bookmark data, sufficient pre-SnowLeopard alias data will added to the file to allow
			systems running something before SnowLeopard to resolve this file using Alias Manager routines and get back the same file as the bookmark routines.
			The bookmark data must have been created with the kCFURLBookmarkCreationSuitableForBookmarkFile option and an error will be returned if not.
