/**
* endian - endian conversion macros for simple types
*
* Portable protocols (such as on-disk formats, or network protocols)
* are often defined to be a particular endian: little-endian (least
* significant bytes first) or big-endian (most significant bytes
* first).
*
* Similarly, some CPUs lay out values in memory in little-endian
* order (most commonly, Intel's 8086 and derivatives), or big-endian
* order (almost everyone else).
*
* This module provides conversion routines, inspired by the linux kernel.
* It also provides leint32_t, beint32_t etc typedefs, which are annotated for
* the sparse checker.
*
* Example:
* #include <stdio.h>
* #include <err.h>
* #include <ccan/endian/endian.h>
*
* //
* int main(int argc, char *argv[])
* {
* uint32_t value;
*
* if (argc != 2)
* errx(1, "Usage: %s <value>", argv[0]);
*
* value = atoi(argv[1]);
* printf("native: %08x\n", value);
* printf("little-endian: %08x\n", cpu_to_le32(value));
* printf("big-endian: %08x\n", cpu_to_be32(value));
* printf("byte-reversed: %08x\n", bswap_32(value));
* exit(0);
* }
