## Function Documentation

## ◆ elm_cache_all_flush()

void elm_cache_all_flush | ( | void |  | ) |

Flush all caches.

Frees all data that was in cache and is not currently being used to reduce memory usage. This frees Edje's, Evas' and Eet's cache. This is equivalent to calling all of the following functions:

- edje_file_cache_flush()
- edje_collection_cache_flush()
- eet_clearcache()
- evas_image_cache_flush()
- evas_font_cache_flush()
- evas_render_dump()
  Note
    Evas caches are flushed for every canvas associated with a window.

## ◆ elm_config_cache_flush_interval_get()

int elm_config_cache_flush_interval_get | ( | void |  | ) |

Get the configured cache flush interval time.

This gets the globally configured cache flush interval time, in ticks

Returns
  The cache flush interval time

See also
  elm_cache_all_flush()

## ◆ elm_config_cache_flush_interval_set()

void elm_config_cache_flush_interval_set | ( | int | size | ) |

Set the configured cache flush interval time.

This sets the globally configured cache flush interval time, in ticks

Parameters

  size | The cache flush interval time

Note
  The `size` must be greater than 0. if not, the cache flush will be ignored.

See also
  elm_cache_all_flush()

References EINA_SAFETY_ON_FALSE_RETURN, and EINA_TRUE.

## ◆ elm_config_cache_flush_enabled_get()

Eina_Bool elm_config_cache_flush_enabled_get | ( | void |  | ) |

Get the configured cache flush enabled state.

This gets the globally configured cache flush state - if it is enabled or not. When cache flushing is enabled, elementary will regularly (see elm_config_cache_flush_interval_get() ) flush caches and dump data out of memory and allow usage to re-seed caches and data in memory where it can do so. An idle application will thus minimize its memory usage as data will be freed from memory and not be re-loaded as it is idle and not rendering or doing anything graphically right now.

Returns
  The cache flush state

See also
  elm_cache_all_flush()

## ◆ elm_config_cache_flush_enabled_set()

void elm_config_cache_flush_enabled_set | ( | Eina_Bool | enabled | ) |
