[cpp]
unsigned xor_hash ( void *key, int len )
{
unsigned char *p = key;
unsigned h = 0;
int i;
for ( i = 0; i < len; i++ )
h ^= p[i];
return h;
}
[cpp]

here is another and better one
[cpp]
unsigned rot_hash ( void *key, int len )
{
unsigned char *p = key;
unsigned h = 0;
int i;

for ( i = 0; i < len; i++ )
h = ( h << 4 ) ^ ( h >> 28 ) ^ p[i];

return h;
}
[/cpp]
