Example:

import std/inotify
when defined(linux):
  let inoty: FileHandle = inotify_init()           ## Create 1 Inotify.
  doAssert inoty >= 0                              ## Check for errors (FileHandle is alias to cint).
  let watchdoge: cint = inotify_add_watch(inoty, ".", IN_ALL_EVENTS) ## Add directory to watchdog.
  doAssert watchdoge >= 0                          ## Check for errors.
  doAssert inotify_rm_watch(inoty, watchdoge) >= 0 ## Remove directory from the watchdog
