  25  This API returns the various standard system directories where apps, resources, etc get installed.
  26  Because queries can return multiple directories, the API is in the form of an enumeration.
  27  The directories are returned in search path order; that is, the first place to look is returned first.
  28  This API may return directories that do not exist yet.
  29  If NSUserDomain is included in a query, then the results will contain "~" to refer to the user's directory.
  30  NEXT_ROOT is prepended as necessary to the returned values.
  31  Some calls might return no directories!
  32  The buffer that is passed in will be filled with a null-terminated string, possibly containing as many as PATH_MAX-1 characters.
  33
  34  Typical usage:
  35
  36     #include <limits.h>
  37     #include <NSSystemDirectories.h>
  38
  39     char path[PATH_MAX];
  40     NSSearchPathEnumerationState state = NSStartSearchPathEnumeration(dir, domainMask);
  41     while (state = NSGetNextSearchPathEnumeration(state, path)) {
  42         // Handle path
  43     }
