calculate()

static unsigned int bdlde::Crc32c::calculate ( const void *  data, bsl::size_t  length, unsigned int  crc = k_NULL_CRC32C  )

static

Return the CRC32-C value calculated for the specified data over the specified length number of bytes, using the optionally specified crc value as the starting point for the calculation.

Note

Note that if data is 0, then length also must be 0.

k_NULL_CRC32C

const unsigned int bdlde::Crc32c::k_NULL_CRC32C = 0U

static

CRC32-C value for a 0 length input.

Note

Note that a buffer with this CRC32-C value need not be a 0 length input.
