DESCRIPTION

28       These  routines swap between LSBF (little-endian) and MSBF (big-endian)
29       byte orders.  The specified quantities are swapped in-place.  There are
30       two  versions  of most routines: a generic one that works on quantities
31       regardless of memory alignment (ms_gswap#) and one that works on memory
32       aligned quantities (ms_gswap#a).  The versions for memory aligned quan‐
33       tities are much faster than their  generic  versions,  but  the  memory
34       *must*  be aligned.  You have been warned. There is only a generic ver‐
35       sion for 3-byte quantities.
