I'm implementing the mylsl.c (which is equivalent to "ls -l") method for Unix. Everything is set pretty much, except the contents of the current directory is being shown in a random order.
How could I sort the contents by filename?

@Tim sorry, I guess maybe it's because I'm not really familiar with the system.. How should I do that? (I mean there're several options like "Was it helpful?" and etc. Which one is it?Emil– Emil2011-10-20 02:47:45 +00:00Commented Oct 20, 2011 at 2:47

The general solution to this problem is:
- Read all the directory entries (into memory)
- Sort them
- Write them out in sorted order
The OS does not provide a way to list them in sorted order for you.

@Emil: Yep. The system wants to make sure there's time for other answers to be posted, so you can accept the best one.
