Method

GioFilemonitor_file

Declaration

GFileMonitor*
g_file_monitor_file (
  GFile* file,
  GFileMonitorFlags flags,
  GCancellable* cancellable,
  GError** error
)

Description

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 G_IO_ERROR_CANCELLED will be returned.

If flags contains G_FILE_MONITOR_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 GFileMonitor backend and/or filesystem type.

Parameters

flags GFileMonitorFlags
 

A set of GFileMonitorFlags.

cancellable GCancellable
 

Optional GCancellable object, NULL to ignore.

 The argument can be NULL.
 The data is owned by the caller of the function.
error GError **
  The return location for a GError*, or NULL.

Return value

Returns: GFileMonitor
 

A GFileMonitor for the given file, or NULL on error. Free the returned object with g_object_unref().

 The caller of the method takes ownership of the data, and is responsible for freeing it.
