Hello team,

Can you please let me know, when using *mdb_cursor_get* with *MDB_SET* operation, in case the key is not present in the db, where is the cursor left pointing?

My scenario is that i want to retrieve two adjacent keys.

1. first *mdb_cursor_get* with *MDB_SET*
2. after that, *mdb_cursor_get* with *MDB_NEXT*

I'm wondering what can i expect the cursor to point at in case the key is not found in step 1.

You cannot expect anything in particular.

Use MDB_SET_RANGE instead.
