Discussion of [NSDictionary NSFileType]

This and the other file... methods are for use with a dictionary, such as those returned from the methods fileAttributesAtPath:traverseLink: (NSFileManager), directoryAttributes(NSDirectoryEnumerator), and fileAttributes (NSDirectoryEnumerator), that represents the POSIX attributes of a file or directory. This method returns the file’s type. Possible return values are described in the “Constants” section of NSFileManager.

Example of [NSDictionary NSFileType]

NSFileManager *filemgr;
NSDictionary *attribs;

filemgr = [NSFileManager defaultManager];

attribs = [filemgr attributesOfItemAtPath: @"/tmp" error: NULL];

NSLog (@"Created on %@", [attribs objectForKey: NSFileCreationDate]);
NSLog (@"File type %@", [attribs objectForKey: NSFileType]);
NSLog (@"POSIX Permissions %@", [attribs objectForKey: NSFilePosixPermissions]);
