unsigned int gr_crc32 (  const std::string  buf  )

unsigned int gr_crc32 (  const unsigned char *  buf, int  len )

unsigned int gr_update_crc32 (  unsigned int  crc, const std::string  buf )

unsigned int gr_update_crc32 (  unsigned int  crc, const unsigned char *  buf, int  len )

update running CRC-32 Update a running CRC with the bytes buf[0..len-1] The CRC should be initialized to all 1's, and the transmitted value is the 1's complement of the final running CRC. The resulting CRC should be transmitted in big endian order.
