This is a two\-argument function .B f such that .B f e1 e2 is zero if the keys .B e1 and .B e2 are equal, .B f e1 e2 is strictly negative if .B e1 is smaller than .B e2 , and .B f e1 e2 is strictly positive if .B e1 is greater than .B e2 \&. Example: a suitable ordering function is the generic structural comparison function .B Pervasives\&.compare \&. .sp
