| Eio_Done_Cb | done_cb, | ||
| Eio_Eet_Error_Cb | error_cb, | ||
| const void * | data | ||
| ) |
Close an eet file handle and flush pending writes asynchronously.
- Parameters:
-
ef A valid eet file handle. done_cb Callback called from the main loop when the file has been closed. error_cb Callback called in the main loop when the file can't be closed. data Unmodified user data passed to callbacks
- Returns:
- NULL in case of a failure.
This function will call eet_close() from another thread by using Ecore_Thread. You should assume that the Eet_File is dead after this function is called.
