NAME

       strhash - hash function for strings

SYNOPSIS

       #include <publib.h>
       unsigned long strhash(const char *s);

DESCRIPTION

       strhash  is  a  hash  function for strings.  It uses an algorithm that tries to be good in
       most cases, but it is often possible to use a better  algorithm  that  takes  better  into
       account  the  characteristics of the data for a given application.  However, strhash often
       good enough; test it before spending time to develop a better one.

RETURN VALUE

       strhash returns the computed hash value.  Note that the  value  is  not  scaled  into  any
       particular  range  (all  values  that an unsigned long can take are possible).  The caller
       will have to do the scaling himself.
