* BSD NETWORK WORD ORDER - TO - CPU WORD ORDER MACRO'S
*
* Description : Convert data values to & from network word order to host CPU word order.
*
* Argument(s) : val Data value to convert (see Note #2).
*
* Return(s) : Converted data value (see Note #2).
*
* Caller(s) : Application.
*
* These macro's are network protocol suite application interface (API) macro's & MAY be
* called by application function(s).
*
* Note(s) : (1) BSD 4.x macro's are required only for applications that call BSD 4.x macro's.
*
* See also 'MODULE Note #1b1'.
*
* (2) 'val' data value to convert & any variable to receive the returned conversion MUST
* start on appropriate CPU word-aligned addresses. This is required because most word-
* aligned processors are more efficient & may even REQUIRE that multi-octet words start
* on CPU word-aligned addresses.
*
* (a) For 16-bit word-aligned processors, this means that
*
* all 16- & 32-bit words MUST start on addresses that are multiples of 2 octets
*
* (b) For 32-bit word-aligned processors, this means that
*
* all 16-bit words MUST start on addresses that are multiples of 2 octets
* all 32-bit words MUST start on addresses that are multiples of 4 octets
*
* See also 'net_util.h NETWORK WORD ORDER - TO - CPU WORD ORDER MACRO'S Note #1'.
