## Function Documentation

Efreet_Desktop* efreet_desktop_get | ( | const char * | file | ) |

Gets a reference to an Efreet_Desktop structure representing the contents of file or NULL if file is not a valid .desktop file.

Parameters

  file | The file to get the Efreet_Desktop from

Returns
  Returns a reference to a cached Efreet_Desktop on success, NULL on failure By using efreet_desktop_get the Efreet_Desktop will be saved in an internal cache for quicker loading.

Users of this command should listen to EFREET_EVENT_DESKTOP_CACHE_UPDATE event, if the application is to keep the reference. When the event fires the Efreet_Desktop struct should be invalidated and reloaded from a new cache file.

int efreet_desktop_ref | ( | Efreet_Desktop * | desktop | ) |

Increases reference count on desktop.

Parameters

  desktop | The Efreet_Desktop to ref

Returns

Parameters

  file | The file to get the Efreet_Desktop from

Returns
  Returns a reference to a cached Efreet_Desktop on success, NULL on failure Users of this command should listen to EFREET_EVENT_DESKTOP_CACHE_UPDATE event, if the application is to keep the reference. When the event fires the Efreet_Desktop struct should be invalidated and reloaded from a new cache file.

Parameters

  file | The file to create the Efreet_Desktop from

Returns
  Returns a new Efreet_Desktop on success, NULL on failure By using efreet_desktop_uncached_new the Efreet_Desktop structure will be read from disk, and not from any cache.

Data in the structure is allocated with strdup, so use free and strdup to change values.
