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.
