/**
 * crc - routines for crc of bytes
 *
 * Cyclic Redundancy Check routines.  These are reasonably fast
 * checksum routines, but not suitable for cryptographic use.
 *
 * They are useful for simple error detection, eg. a 32-bit CRC will
 * detect a single error burst of up to 32 bits.
 *
 * Example:
 *	#include <ccan/crc/crc.h>
 *	#include <stdio.h>
 *	#include <stdlib.h>
 *
 *	// Given "IHATEMATH" outputs 0x98a3b8df
 *	int main(int argc, char *argv[])
 *	{
 *		if (argc != 2) {
 *			fprintf(stderr, "Usage: %s <string>\n"
 *				"Prints 32 bit CRC of the string\n", argv[0]);
 *			exit(1);
 *		}
 *		printf("0x%08x\n", crc32c(0, argv[1], strlen(argv[1])));
 *		exit(0);
 *	}
