NAME

       ms_gswap - Generalized, in-place byte swapping routines

SYNOPSIS

       #include <libmseed.h>

       void  ms_gswap2 ( void *data2 );

       void  ms_gswap3 ( void *data3 );

       void  ms_gswap4 ( void *data4 );

       void  ms_gswap8 ( void *data8 );

       void  ms_gswap2a ( void *data2 );

       void  ms_gswap4a ( void *data4 );

       void  ms_gswap8a ( void *data8 );

DESCRIPTION

       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.
