Gio.File.prototype.monitor_file

function monitor_file(flags: Gio.FileMonitorFlags, cancellable: Gio.Cancellable): Gio.FileMonitor {
    // Gjs wrapper for g_file_monitor_file()
}
  

Obtains a file monitor for the given file. If no file notification mechanism exists, then regular polling of the file is used.

If cancellable is not null, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error Gio.IOErrorEnum.cancelled will be returned.

If flags contains Gio.FileMonitorFlags.watch_hard_links then the monitor will also attempt to report changes made to the file via another filename (ie, a hard link). Without this flag, you can only rely on changes made through the filename contained in file to be reported. Using this flag may result in an increase in resource usage, and may not have any effect depending on the Gio.FileMonitor backend and/or filesystem type.
