+ SYNOPSIS
+ hashcmp()
+ hash hash table
+ pos position of hash record to use in comparison
+ key key for comparison
+ length length of key
+
+ NOTES:
+ If length is 0, comparison is done using the length of the
+ record being compared against.
+
+ RETURN
+ < 0 key of record < key
+ = 0 key of record == key
+ > 0 key of record > key
