Method Filesystem.Monitor.basic()->file_exists()

Method file_exists

void file_exists(string path, Stdio.Stat st)

Description

File existance callback.

Parameter path

Path of the file or directory.

Parameter st

Status information for path as obtained by file_stat(path, 1).

This function is called during initialization for all monitored paths, and subpaths for monitored directories. It represents the initial state for the monitor.

Note

For directories, file_exists() will be called for the subpaths before the call for the directory itself. This can be used to detect when the initialization for a directory is finished.

Called by check() and check_monitor() the first time a monitored path is checked (and only if it exists).

Overload this to do something useful.

Note

This callback has similar semantics to file_created(), but is called at initialization time.
