BloombergLP::bdlde::Crc32c::calculate

Synopsis

Declared in <bdlde_crc32c.h>

static
unsigned int
calculate(
    void const* data,
    std::size_t length,
    unsigned int crc = k_NULL_CRC32C);

Description

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

Return Value

the CRC32-C checksum of the specified data

Parameters

Name	Description
data	memory region to checksum
length	number of bytes in `data`
crc	starting CRC32-C value for the calculation
