The FindVarMethod routine will be given an OID, and attempts to return the next valid OID within that table. If it can't then it returns NULL to indicate failure. That's all it knows about. The main agent code has a list of registered tables. When it receives an SNMP request, it identifies the table that this request refers to, and calls that FindVarMethod (or v5 equivalent) to provide the appropriate results. If the table handler returns NULL, then the agent moves on to the next table, and so on. So it's the agent driving code that jumps from one table to the next, not the code for the individual tables.
