Return a 32-bit hash value for the specified data of the specified length.

unsigned int
hash1(
char const* data,
int length);Return an unsigned integer hash value corresponding to the specified data of the specified length (in bytes). The behavior is undefined unless 0 <= length. Note that if data is 0, then length also must be 0. Also note that every byte in data is significant; that is, it is not appropriate to cast a struct address to a char * unless the struct is packed (no padding).
Both hash1 and hash2 return a hash, but both hashes can be assumed to be independent (i.e., there are no known correlations between the results of the two hash functions given the same input data).
