From d718ded056eefb6239bd2e0a57b7f6d99c6e9e4b Mon Sep 17 00:00:00 2001 From: Przemyslaw Marczak Date: Wed, 2 Apr 2014 10:20:03 +0200 Subject: lib: uuid: code refactor for proper maintain between uuid bin and string Changes in lib/uuid.c to: - uuid_str_to_bin() - uuid_bin_to_str() New parameter is added to specify input/output string format in listed functions This change allows easy recognize which UUID type is or should be stored in given string array. Binary data of UUID and GUID is always stored in big endian, only string representations are different as follows. String byte: 0 36 String char: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx string UUID: be be be be be string GUID: le le le be be This patch also updates functions calls and declarations in a whole code.
