Constants

• BYTE_EXTENSION_TABLE
• CRC32XOR
  | CRCs are pre- and post- conditioned | by xoring with all ones. |
• MASK_DELTA
• STRIDE_EXTENSION_TABLE0
• STRIDE_EXTENSION_TABLE1
• STRIDE_EXTENSION_TABLE2
• STRIDE_EXTENSION_TABLE3

Functions

• crc32c_can_accelerate
  | Determine if the CPU running this program | can accelerate the CRC32C calculation. |
• crc32c_extend
  | Return the crc32c of concat(A, data[0,n-1]) | where init_crc is the crc32c of some string A. | Extend() is often used to maintain the crc32c | of a stream of data.
• crc32c_mask
  | Return a masked representation of crc. | | Motivation: it is problematic to compute the | CRC of a string that contains embedded CRCs. | Therefore we recommend that CRCs stored | somewhere (e.g., in files) should be masked | before being stored.
• crc32c_read_uint32le
  | Reads a little-endian 32-bit integer | from a 32-bit-aligned buffer. |
• crc32c_round_up
  | Returns the smallest address >= the given | address that is aligned to N bytes. | | N must be a power of two.
• crc32c_unmask
  | Return the crc whose masked representation | is masked_crc. |
• crc32c_value
  | Return the crc32c of data[0,n-1] |
