Spore:HashVal

The following was originally written by Jongware.

This "C" routine will calculate the hash for a Spore item. In my version, the strcpy() and temporary buffer exist to avoid modifying the original string when converting to lower case with _strlwr(). If the original need not be saved, this could be further optimized.

unsigned long TheHash(char *strptr) {
	char oname[STRMAX];
	unsigned int hash;
	char *p;

	strcpy(&oname[0], strptr);
	_strlwr(&oname[0]);
	hash = 0x811C9DC5;
	p=&oname[0];
	while(*p) {
		hash *= 0x1000193;
		hash ^= (*p);
		p++;
		}
	return(hash);
	}
