Net-SNMP 表格

/** returns the first data point within the portSetTable table data.


    Set the my_loop_context variable to the first data point structure
    of your choice (from which you can find the next one).  This could
    be anything from the first node in a linked list, to an integer
    pointer containing the beginning of an array variable.


    Set the my_data_context variable to something to be returned to
    you later that will provide you with the data to return in a given
    row.  This could be the same pointer as what my_loop_context is
    set to, or something different.


    The put_index_data variable contains a list of snmp variable
    bindings, one for each index in your table.  Set the values of
    each appropriately according to the data matching the first row
    and return the put_index_data variable at the end of the function.
