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.
