I've done the obvious of obliterating any "..", but I know that there are many more ways to bypass this.

You could:

  1. Save the current directory
  2. chdir() to the directory in question
  3. get the new current directory
  4. chdir() back to the saved directory
  5. return the "new current directory" from step 3
solving at least one problem.

From that point, you may have to brute-force search the resulting pathname (e.g., split() on '/', examine each component, etc.)

Perhaps not that helpful ... sorry.
