Virtual Method

GioFilemonitor_dir

Declaration [src] 

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

Description [src]

Obtains a directory monitor for the given file. This may fail if directory monitoring is not supported.

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.

It does not make sense for flags to contain G_FILE_MONITOR_WATCH_HARD_LINKS, since hard links can not be made to directories. It is not possible to monitor all the files in a directory for changes made via hard links; if you want to do this then you must register individual watches with g_file_monitor().

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.
