Detailed Description
CRC32 implementation
Created Aug 10, 2011 Vasil Dimov
Typedef Documentation
| typedef ib_uint32_t(* ib_ut_crc32_t)(const byte *ptr, ulint len) |
Calculates CRC32.
- Parameters
-
ptr - data over which to calculate CRC32. len - data length in bytes.
- Returns
- CRC32 (CRC-32C, using the GF(2) primitive polynomial 0x11EDC6F41, or 0x1EDC6F41 without the high-order bit)
Function Documentation
| UNIV_INTERN void ut_crc32_init | ( | ) |
Initializes the data structures used by ut_crc32(). Does not do any allocations, would not hurt if called twice, but would be pointless.
