The fchown function takes four arguments:

1. fileDescriptor: A file descriptor, obtained by opening the file using fs.openSync() or fs.open().
2. uid: An integer representing the user ID of the new file owner.
3. gid: An integer representing the group ID of the new file owner.
4. callback: A callback function that will be called after the file owner has been changed. This function will be passed an error object if there was an error, or null if the operation was successful.

Note that the fchown function is only available on platforms that support it. It may not work on all operating systems.
