Which is more efficient (ie: cheaper and faster) in a program?
- to chdir("/path") and then unlink("file") for each file in the
directory
-OR-
- to explicity unlink("/path/file") for dozens of files in each
directory?
And does the recommended method used vary based on Sys V or BSD 4.2/3 ??
I will be removing hundreds of files in hundreds of directories
at a shot with this approach.
Please E-Mail to me and I will summarize and re-post.

But does not unlink() have to chase back up the directory structures (re-construct the directory tree) in order to ascertain if the correct permissions exist to allow removal of the file? Therefore, would not calling unlink() with the full pathname be more efficient, since all information is provided to unlink() about the path? >Please E-Mail to me and I will summarize and re-post. thanks, paul -- -- Paul Anderson * h:404-565-0761 w:841-4000 {mathcs.emory,gatech}.edu!stiatl!pda || pda@SalesTech.Com
