+ * @brief Macros for byteswapping
+ * 
+ * These macros are for converting integer types from and to big endian or little endian.
+ * They abstract from the endianness of your system by providing a different implementation based on the value of DDSRT_ENDIAN
+ * (for example if you want to convert to big endian, it converts if your system is little endian,
+ * but if your system is already big endian, the conversion is skipped).
+ * Postfix numbers indicate the number of bytes of the integer (2,4,8 for 16-bit, 32-bit, 64-bit respectively),
+ * whilst an 'u' postfix indicates an unsigned integer type.
+ * 
+ * - ddsrt_toBE: convert from native to big endian
+ * - ddsrt_toLE: convert from native to little endian
+ * - ddsrt_toBO: convert from native to byte order 'bo', @see ddsrt_byte_order_selector
+ * - ddsrt_fromBE: convert from big endian to native endianness (DDSRT_ENDIAN)
