* These functions byte swap and other manipulations on
|
|
* DtSearch or_... structures to ensure that database records
|
|
* are maintained in a canonical format no matter what machine
|
|
* they are used on.
|
|
* The functions use the standard htonl, htons, ntohl, and ntohs
|
|
* network conversion functions for byte order neutrality.
|
|
* They use the DtSrINT16 and DtSrINT32 typedefs in Search.h
|
|
* to control integer size.
|
|
* The external database records are in the canonical,
|
|
* big-endian "network" order.
|
|
* So that they can be defined as "null" macros on big endian machines,
|
|
* the functions (1) always byte swap in place and (2) always succeed.
