Detailed Description

These function monitor changes in directories and files.

These functions use the best available method to monitor changes on a specified directory or file. They send ecore events when changes occur, and they maintain internal refcounts to reduce resource consumption on duplicate monitor targets.

Function Documentation

EAPI Eio_Monitor* eio_monitor_add ( const char *  path)

Adds a file/directory to monitor (inotify mechanism)

Parameters
pathfile/directory to monitor
Returns
NULL in case of a failure or a pointer to the monitor in case of success.

This function will add the given path to its internal list of files to monitor. It utilizes the inotify mechanism introduced in kernel 2.6.13 for passive monitoring.

References eina_stringshare_add(), eina_stringshare_del(), and eio_monitor_stringshared_add().

EAPI Eio_Monitor* eio_monitor_stringshared_add ( const char *  path)

Adds a file/directory to monitor.

Parameters
pathfile/directory to monitor
Returns
NULL in case of a failure or a pointer to the monitor in case of success.
Warning
Do NOT pass non-stringshared strings to this function! If you don't know what this means, use eio_monitor_add().

This fuction is just like eio_monitor_add(), however the string passed by argument must be created using eina_stringshare_add().

Referenced by eio_monitor_add().

EAPI void eio_monitor_del ( Eio_Monitor *  monitor)

Deletes a path from the “watched” list.

Parameters
monitorThe Eio_Monitor you want to stop watching. It can only be an Eio_Monitor returned to you from calling eio_monitor_add() or eio_monitor_stringshared_add()

References EINA_REFCOUNT_UNREF.

EAPI const char* eio_monitor_path_get ( Eio_Monitor *  monitor)

returns the path being watched by the given Eio_Monitor.

Parameters
monitorEio_Monitor to return the path of
Returns
The stringshared path belonging to monitor

Variable Documentation

EAPI int EIO_MONITOR_FILE_CLOSED

A file was closed in a watched directory.

This event is never sent on Windows

EAPI int EIO_MONITOR_DIRECTORY_CLOSED

A directory has been closed in a watched directory.

This event is never sent on Windows

EAPI int EIO_MONITOR_ERROR

During operation the monitor failed and will no longer work.

eio_monitor_del must be called on it.
