Virtual Method

GioFilemonitor_file

Declaration [src]

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

Description [src]

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

Type: GFileMonitorFlags

A set of GFileMonitorFlags.

cancellable

Type: GCancellable

Optional GCancellable object, NULL to ignore.

The argument can be NULL.

The data is owned by the caller of the method.

error

Type: GError **

The return location for a recoverable error.

The argument can be NULL.

If the return location is not NULL, then you must initialize it to a NULL GError*.

The argument will be left initialized to NULL by the virtual function if there are no errors.

In case of error, the argument will be set to a newly allocated GError; the caller will take ownership of the data, and be responsible for freeing it.

Return value

Type: 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 returned data, and is responsible for freeing it.
