dessertMeshifTable README
------------------------------------------------------------------------
  This readme file describes the code generated by mib2c (using the MIBs
  for Dummies (MFD) configuration file). The code generated was
  generated specifically for the following SNMP table:

     dessertMeshifTable

  Your code will be called when the snmp agent receives requests for
  the dessertMeshifTable table.  The agent will start by looking for the right
  row in your existing data to operate on, if one exists.


  Configuration Variables
  ------------------------------------------------------------
  Some variables used for code generation may be set to affect the code
  generation. You may override these variables by setting them in the
  file defaults/table-dessertMeshifTable.m2d, and then re-running mib2c.

    m2c_table_settable (currently '0')
    --------------------------------------------------------
    This variable determines whether or not code is generated to support
    MIB object which have an access of read-write or read-create. The
    default is set based on whether or not the table contains writable
    objects, but can be over-ridden.

    Syntax: @eval $m2c_table_settable = 0@


    m2c_table_dependencies (currently '0')
    --------------------------------------------------------
    This variable determines whether or not code is generated to support
    checking dependencies between columns, rows or tables. The default
    is set based on whether or not the table contains writable objects,
    but can be over-ridden.

    Syntax: @eval $m2c_table_dependencies = 0@


    m2c_table_row_creation (currently '0')
    --------------------------------------------------------
    This variable determines whether or not code is generated to support
    checking creation of new rows via SNMP. The default is set based on
    whether or not the table contains read-create objects, but can be
    over-ridden.

    Syntax: @eval $m2c_table_row_creation = 0@


    m2c_context_reg (currently 'netsnmp_data_list')
    --------------------------------------------------------
    This variable contains the structure name to typedef for the
    dessertMeshifTable_registration.

    During initilization, you will provide a pointer to a structure of
    this type. This pointer is used as a parameter to many functions so
    that you have access to your registration data. The default is a
    netsnmp_data_list pointer, which will allow you to keep multiple
    pointers tagged by a text name. If you have a new or existing structure
    you would rather use, you can redefine this variable.
    

    To avoid regenerating code, you may also change this typedef directly
    in the dessertMeshifTable.h header.

    Syntax: @eval $m2c_context_reg = "struct my_registration_context@


    m2c_data_context (currently 'generated')
    --------------------------------------------------------
    This variable contains the structure name to typedef for the
    dessertMeshifTable_data.

    This typedef is used in the row request context structure for the table,
    dessertMeshifTable_rowreq_ctx.

    The typedef in the primary table context will be used for the data and
    undo structure types. This structure should contain all the data
    needed for all the columns in the table. The default is 'generated',
    which will cuase a new data strcuture to be generated with data members
    for each column.

    To avoid regenerating code, you may also change this typedef directly
    in the dessertMeshifTable.h header.

    Syntax: @eval $m2c_data_context = "struct my_data_context"@


    m2c_data_allocate (currently '0')
    --------------------------------------------------------
    This variable determines whether or not the data context (see above)
    requires memory to be allocated. The default generated data structure
    does not. If you are using a custom data context which needs to
    allocate memory, override this value and two additional functions
    will be generated:

      dessertMeshifTable_allocate_data
      dessertMeshifTable_release_data

    Syntax: @eval $m2c_data_allocate = 1@


    m2c_data_init (currently '1')
    --------------------------------------------------------
    This variable determines whether or not the data context (see above)
    or any other items you have added to the table context requires
    initialization. The default generated data structure does not. If you
    are using a custom data context or have added items needing initialization
    to the table context, override this value and two additional functions
    will be generated:

      dessertMeshifTable_rowreq_ctx_init
      dessertMeshifTable_rowreq_ctx_cleanup

    Syntax: @eval 1 = 1@


    m2c_table_access (currently 'container-cached')
    ------------------------------------------------------------------
    This variable determines which data interface will be use to generate
    code for looking up data for a given index. The default is the
    'container-cached' access code, which caches the data in a netsnmp-
    container (usually a sorted array).

    Available options can be determined by checking for mib2c configuration
    files that begin with 'mfd-access-*'.

    Syntax: @eval $m2c_table_access = 'container-cached'@

 
    m2c_include_examples (currently '1')
    ------------------------------------------------------------------
    This variable determines whether or not to generate example code. The
    default is to generate example code.

    Syntax: @eval $m2c_include_examples = 0@


    m2c_data_transient (currently '0')
    ------------------------------------------------------------------
    This variable determines how the generated example code deals with the
    data during data lookup. See the table readme file for details on how
    the current table access method interprets this value. In general,
    a value of 0 indicates persistent data, 1 indicates semi-transient and
    2 indicates transient data.

    Syntax: @eval $m2c_data_transient = 0@


 Index(es) for the dessertMeshifTable table
  ------------------------------------------------------------
  The index(es) for the dessertMeshifTable table are:

     meshifIndex:
        Syntax:      
        DataType:    
        ASN type:    
        C-code type: 

  You should know how to set all these values from your data context,
  dessertMeshifTable_data.


************************************************************************
dessertMeshifTable File Overview
------------------------------------------------------------------------
  Several files have been generated to implement the dessertMeshifTable
  table. We'll go through these files, one by one, explaining each and
  letting you know which you need to edit.


File: dessertMeshifTable_data_access.[c|h]
------------------------------------------------------------------------
  The dessertMeshifTable_data_access file contains the interface to your data in
  its raw format.  These functions are used to build the row cache or 
  locate the row (depending on the table access method).

  Set MIB context
  -----------------
  TODO : Set MIB index values
  FUNC : dessertMeshifTable_indexes_set
  WHERE: dessertMeshifTable_data_access.c

  This is a convenience function for setting the index context from
  the native C data. Where necessary, value mapping should be done.

  This function should update the table index values (found in
  tbl_idx) for the given raw data.

  
  container summary
  ------------------------
    The container data access code is for cases when you want to
    store your data in the agent/sub-agent.

    ... to be continued...


  cache summary
  ------------------------
    The container-cached data access code is for cases when you want to
    cache your data in the agent/sub-agent.

    ... to be continued...




File: dessertMeshifTable_enums.h
------------------------------------------------------------------------
  This file contains macros for mapping enumeration values when the
  enumerated values defined by the MIB do not match the values used
  internally.

  Review this file to see if any values need to be updated.


File: dessertMeshifTable_data_get.c
------------------------------------------------------------------------
  Get data for column
  -------------------
  TODO : retrieve column data from raw data
  FUNC : meshifName_get

  Get data for column
  -------------------
  TODO : retrieve column data from raw data
  FUNC : meshifMacAddress_get

  Get data for column
  -------------------
  TODO : retrieve column data from raw data

  -------------------
  TODO : retrieve column data from raw data
  FUNC : meshifInOctets_get

  Get data for column
  -------------------
  TODO : retrieve column data from raw data
  FUNC : meshifOutOctets_get



File: dessertMeshifTable_data_set.c
------------------------------------------------------------------------

  This table does not support set requests.

Function flow
----------------------------------------------------
To give you the general idea of how the functions flow works, this
example flow is from a complete table implementation.

NOTE: Depending on your configuration, some of the functions used in the
      examples below  may not have been generated for the
      dessertMeshifTable table.

      Conversely, the examples below may not include some functions that
      were generated for the dessertMeshifTable table.

To watch the flow of the dessertMeshifTable table, use the
following debug tokens:

        snmp_agent
        helper:table:req
        dessertMeshifTable
        verbose:dessertMeshifTable
        internal:dessertMeshifTable
