key: The resource key that identifies the resource property.
Value: On output when the result is true, the resource value or nil.
error: On output when the result is false, the error that occurred.

Returns true if value is successfully populated; false if an error occurs.

ResourcePropertyForKey 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 ResourcePropertyForKey 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 v alue is populated with nil, 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.

key: The resource key that identifies the resource property.
Value: The resource value.
error: On output when the result is false, the error that occurred.

Returns true if the attempt to set the resource value completed with no errors; otherwise, false.

CFURLSetResourcePropertyForKey writes the new resource value out to the backing store. Attempts to set a read-only resource property or to set a resource property not supported by the resource are ignored and are not considered errors. If this function returns false, the optional error is populated. This function is currently applicable only to URLs for file system resources.
