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.
[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. |
