Thanks for the tips!

Considering that $buf might have multiple dentries inside of it, how do I navigate thru all those records? For C is easy because I'm accessing memory directly, but how do I know how many bytes I should read from $buf and how to move to the next record with Perl?

I've already put it in the code. The variable $len contains total length of single dirent structure. So, all you have to do is to remove this many bytes from the beginning of the buffer.	[reply]
