hash()
- Method
hash
int hash(string s)
int hash(string s, int max)- Description
Return an integer derived from the string s . The same string always hashes to the same value, also between processes, architectures, and Pike versions (see compatibility notes below, though).
If max is given, the result will be >= 0 and < max , otherwise the result will be >= 0 and <= 0x7fffffff.
- Note
The hash algorithm was changed in Pike 7.5. If you want a hash that is compatible with Pike 7.4 and earlier, use 7.4::hash() . The difference only affects wide strings.
The hash algorithm was also changed in Pike 7.1. If you want a hash that is compatible with Pike 7.0 and earlier, use 7.0::hash() .
