- * e_util_read_file:
- * @filename: File name to read.
- * @filename_is_uri: Whether the file name is URI, if not, then it's a local path.
- * @buffer: Read content or the file. Should not be NULL. Returned value should be freed with g_free.
- * @read: Number of actually read bytes. Should not be NULL.
- * @error: Here will be returned an error from reading operations. Can be NULL. Not every time is set when returned FALSE.
- *
- * Reads synchronously content of the file, to which is pointed either by path or by URI.
- * Mount point should be already mounted when calling this function.
- *
- * Returns: Whether was reading successful or not.
