do a perror after every system call that you call ....perhaps that directory is not even present. are you including all the correct headers? to get the compilation done atleast?
is it compiling fine?
isf yes where do you get the error?

Your fopen() call needs to use buf instead of entry->d_name. I typo'd the code that I posted in your other thread. My apologies.

Your closedir() call is also a little whacked. You should change it to just closedir(dir);. Right now it looks like a function prototype.
