## Function Documentation

## ◆ eet_init()

EAPI int eet_init | ( | void |  | ) |

Initializes the EET library.

The first time this function is called, it will perform all the internal initialization required for the library to function properly and increment the initialization counter. Any subsequent call only increment this counter and return its new value, so it's safe to call this function more than once.

Returns
  The new init count. Will be `0` if initialization failed.

Since
  1.0.0

Examples
  eet-basic.c, eet-data-cipher_decipher.c, eet-data-file_descriptor_01.c, eet-data-file_descriptor_02.c, eet-data-nested.c, eet-data-simple.c, and eet-file.c.

Referenced by edje_init(), efreet_init(), elm_quicklaunch_init(), emotion_init(), and evas_init().

## ◆ eet_shutdown()

EAPI int eet_shutdown | ( | void |  | ) |

Shuts down the EET library.

If eet_init() was called more than once for the running application, eet_shutdown() will decrement the initialization counter and return its new value, without doing anything else. When the counter reaches 0, all of the internal elements will be shutdown and any memory used freed.

Returns
  The new init count.

Since
  1.0.0

Examples
  eet-basic.c, eet-data-cipher_decipher.c, eet-data-file_descriptor_01.c, eet-data-file_descriptor_02.c, eet-data-nested.c, eet-data-simple.c, and eet-file.c.

## ◆ eet_clearcache()

EAPI void eet_clearcache | ( | void |  | ) |

Clears eet cache.

For a faster access to previously accessed data, Eet keeps an internal cache of files. These files will be freed automatically only when they are unused and the cache gets full, in order based on the last time they were used. On systems with little memory this may present an unnecessary constraint, so eet_clearcache() is available for users to reclaim the memory used by files that are no longer needed. Those that were open using EET_FILE_MODE_WRITE or EET_FILE_MODE_READ_WRITE and have modifications, will be written down to disk before flushing them from memory.

Since
  1.0.0
