which is a local variable, and so the memory will be discarded when
the routine exits.

These context pointers need to refer to memory that will persist from
one call to another. You can't use a local variable.
These two pointers wouldn't typically refer to the index anyway.
How are the contents of the table stored internally? How would you
most naturally move from one row to the next (ignoring how the MIB
table is indexed), and how would you refer to a row in the table
elsewhere in your application?
That's the way you need to think about these two pointers.
