/**
|
|
* 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);
|
|
* }
