Method 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 hash_7_4() .
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 hash_7_0() .
