pbktCollision
- Points to the next HASHBUCKET in the same slot. Newer buckets are inserted before older buckets, so the ulTime value of the bucket that this member points to is smaller than this bucket's ulTime.
ulTime
- A counter that is incremented for each new HASHBUCKET. FONTHASH::pbktFirst has a value of 0, FONTHASH::pbktLast has the highest value.
pbktPrev
- Pointer to the previous HASHBUCKET, NULL if this is the first
pbktNext
- Pointer to the next HASHBUCKET, NULL if this is the last
wcCapName
- String of upcased font name.
