Macros
#define	BYTE_ORDER   LITTLE_ENDIAN
	Define the byte-order of the platform in use.
#define	arch_swap16(x)
	Swap the byte order of a 16-bit integer.
#define	arch_swap32(x)
	Swap the byte order of a 32-bit integer.
#define	arch_ntohs(x)
	Convert network-to-host short.
#define	arch_ntohl(x)
	Convert network-to-host long.
#define	arch_htons(x)
	Convert host-to-network short.
#define	arch_htonl(x)
	Convert host-to-network long.

Detailed Description

Byte-order related macros.

This file contains architecture-specific byte-order related macros and/or functions. Each platform should define six macros/functions in this file: arch_swap16, arch_swap32, arch_ntohs, arch_ntohl, arch_htons, and arch_htonl. The first two of these swap the byte order of 16-bit and 32-bit integers, respectively. The other four macros will be used by the kernel to implement the network-related byte order functions.
