/**
|
|
* Basic type definitions.
|
|
*
|
|
* This header file defines the generic integer types that will be used
|
|
* for the implementation of hash functions; it also contains helper
|
|
* functions which encode and decode multi-byte integer values, using
|
|
* either little-endian or big-endian conventions.
|
|
*
|
|
* This file contains a compile-time test on the size of a byte
|
|
* (the <code>unsigned char</code> C type). If bytes are not octets,
|
|
* i.e. if they do not have a size of exactly 8 bits, then compilation
|
|
* is aborted. Architectures where bytes are not octets are relatively
|
|
* rare, even in the embedded devices market. We forbid non-octet bytes
|
|
* because there is no clear convention on how octet streams are encoded
|
|
* on such systems.
