#define READ16AT (  adr   )     *((uint16_t*)(adr))

This is to read specific # of bits at given addresses. The cast is done to get rid of the endianness problem.

#define READ8AT (  adr   )     *((uint8_t*)(adr))

Function Documentation

uint32_t hash_computeU16 (  const uint16_t *  data16, size_t  length, uint32_t  initval )

Hash for uint16_t[]. Parameters: length,:  number of uint16_t initval,:  initial value to start the hash computation. Returns: the hash.

uint32_t hash_computeU32 (  const uint32_t *  data, size_t  length, uint32_t  initval )

Compute hash value for different data types. Parameters: length,:  number of uint32_t initval,:  initial value to start the hash computation. Returns: the hash.

uint32_t hash_computeU8 (  const uint8_t *  data8, size_t  length, uint32_t  initval )

Hash for uint8_t[]. Parameters: length,:  number of uint16_t initval,:  initial value to start the hash computation. Returns: the hash.
