How to check whether a file is locked in Cocoa?

Question

Is there any API to check whether a file is a locked? I am not able to find any API in the NSFileManager class.Let me know if there is any API to check the lock of the file.

I found the following link related to file lock

http://lists.apple.com/archives/cocoa-dev/2006/Nov/msg01399.html

I can invoke – isWritableFileAtPath: on file. Is there any other way to find whether a file is locked?

Answer 1

Following Code worked for me.

NSError * error;
NSDictionary *attributes = [[NSFileManager defaultManager] attributesOfItemAtPath:filePath error:&error];
BOOL isLocked = [[attributes objectForKey:NSFileImmutable] boolValue];
            
if (isLocked) {
    NSLog(@"File is locked");
}
