How to use the btree2v API for inserts and reads

[Ankithboggaram]

Hello,

We are trying to integrate your btree2v into our project. We want to use the insert and read APIs, but we are not sure what values to pass to these functions:

extern uid bt_findkey  (BtDb *bt, unsigned char *key, uint len);
extern BTERR  bt_insertkey (BtDb *bt, unsigned char *key, uint len, uint lvl, uid id, uint tod);

As a user of the b-tree, we know the key and value but we are unsure as to how to use this API. Your help would be much appreciated.
