void  ms_gswap2 ( void *data2 );
void  ms_gswap3 ( void *data3 );
void  ms_gswap4 ( void *data4 );

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