opendir() question

[room24]

how do actually use opendir() to open someone's home directory. what value would you pass to opendir on unix to make it open the home directory

I believe that this is what you are asking. You can get the user's home directory by reading the environment variable 'HOME'.

Like this:

  char *homedir;
  DIR *dir;

  homedir = getenv ( "HOME");
  if (NULL == homedir) {} // do something
  else dir = opendir(homedir);

Hope this helps.
