Function for calculating CRC-32 in blocks.
Feed each consecutive data block into this function, along with the current value of p_crc as returned by the previous call of this function. The first call of this function should pass NULL as the initial value of the crc in p_crc.
- Parameters
-
[in] p_data The input data block for computation. [in] size The size of the input data block in bytes. [in] p_crc The previous calculated CRC-32 value or NULL if first call.
- Returns
- The updated CRC-32 value, based on the input supplied.
