Detailed Description

This are helper provided around core Eio API.

This set of functions do provide helper to work around data provided by Eio without the need to look at system header.

Function Documentation

EAPI int eio_init ( void  )

Initialize eio and all it's required submodule.

Returns
the current number of eio users.
Examples:
eio_file_ls.c.

References ecore_init(), eina_init(), eina_log_domain_register(), eina_log_domain_unregister(), EINA_LOG_ERR, eina_log_timing(), and eina_shutdown().

EAPI int eio_shutdown ( void  )

Shutdown eio and all it's submodule if possible.

Returns
the number of pending users of eio.
Examples:
eio_file_ls.c.

References ecore_shutdown(), eina_log_domain_unregister(), eina_log_timing(), eina_shutdown(), and EINA_TRASH_CLEAN.

Referenced by edje_init().

EAPI void* eio_file_container_get ( Eio_File ls)

Return the container during EIO operation.

Parameters
lsThe asynchronous I/O operation to retrieve container from.
Returns
NULL if not available, a DIRP if it is.

This is only available and make sense in the thread callback, not in the mainloop.

References EINA_FALSE.

EAPI Eina_Bool eio_file_cancel ( Eio_File ls)

Cancel any Eio_File.

Parameters
lsThe asynchronous I/O operation to cancel.
Returns
EINA_FALSE if the destruction is delayed, EINA_TRUE if it's done.

This will cancel any kind of I/O operation and cleanup the mess. This means that it could take time to cancel an I/O.

References ecore_thread_cancel(), and EINA_FALSE.

Referenced by emotion_object_file_set().

EAPI Eina_Bool eio_file_check ( Eio_File ls)

Check if an Eio_File operation has been cancelled.

Parameters
lsThe asynchronous I/O operation to check.
Returns
EINA_TRUE if it was canceled, EINA_FALSE other wise.

In case of an error it also return EINA_TRUE.

References ecore_thread_check(), and EINA_TRUE.

EAPI Eina_Bool eio_file_associate_add ( Eio_File ls,
const char *  key,
const void *  data,
Eina_Free_Cb  free_cb 
)

Associate data with the current filtered file.

Parameters
lsThe Eio_File ls request currently calling the filter callback.
keyThe key to associate data to.
dataThe data to associate the data to.
free_cbOptionally a function to call to free the associated data, data is passed as the callback data parameter. If no free_cb is provided the user data remains untouched.
Returns
EINA_TRUE if insertion was fine.

This function can only be safely called from within the filter callback. If you don't need to copy the key around you can use eio_file_associate_direct_add

References EINA_FALSE, eina_hash_add(), and eina_hash_string_small_new().

EAPI Eina_Bool eio_file_associate_direct_add ( Eio_File ls,
const char *  key,
const void *  data,
Eina_Free_Cb  free_cb 
)

Associate data with the current filtered file.

Parameters
lsThe Eio_File ls request currently calling the filter callback.
keyThe key to associate data to (will not be copied, and the pointer will not be used as long as the file is not notified).
dataThe data to associate the data to.
free_cbThe function to call to free the associated data, free_cb will be called if not specified.
Returns
EINA_TRUE if insertion was fine.

This function can only be safely called from within the filter callback. If you need eio to make a proper copy of the key to be safe use eio_file_associate_add instead.

References EINA_FALSE, eina_hash_direct_add(), and eina_hash_string_small_new().

EAPI void* eio_file_associate_find ( Eio_File ls,
const char *  key 
)

Get the data associated during the filter callback inside the main loop.

Parameters
lsThe Eio_File ls request currently calling the notify callback.
keyThe key pointing to the data to retrieve.
Returns
the data associated with the key or NULL if not found.

References eina_hash_find().

static double eio_file_atime ( const Eina_Stat stat)
inlinestatic

get access time from a Eina_Stat

Parameters
statthe structure to get the atime from
Returns
the last accessed time

This take care of doing type conversion to match rest of EFL time API.

Note
some filesystem don't update that information.
static double eio_file_mtime ( const Eina_Stat stat)
inlinestatic

get modification time from a Eina_Stat

Parameters
statthe structure to get the mtime from
Returns
the last modification time

This take care of doing type conversion to match rest of EFL time API.

static long long eio_file_size ( const Eina_Stat stat)
inlinestatic

get the size of the file described in Eina_Stat

Parameters
statthe structure to get the size from
Returns
the size of the file
static Eina_Bool eio_file_is_dir ( const Eina_Stat stat)
inlinestatic

tell if the stated path was a directory or not.

Parameters
statthe structure to get the size from
Returns
EINA_TRUE, if it was.
static Eina_Bool eio_file_is_lnk ( const Eina_Stat stat)
inlinestatic

tell if the stated path was a link or not.

Parameters
statthe structure to get the size from
Returns
EINA_TRUE, if it was.
