Method
GioFilemonitor_file
Declaration [src]
GFileMonitor*
g_file_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.
