Why have an intermediate copy when that's not necessary at all? It seems like pure overhead to be. Furthermore, cpu's have byte-shifting load and store instructions which will be used if you make use of the 'p' versions of the endian swap functions, such as cpu_to_le16p(). So it's going to cost basically nothing. ------------------------------------------------------------------------------ Subversion Kills Productivity. Get off Subversion & Make the Move to Perforce.
