   netsnmp_mib_handler* netsnmp_get_scalar_handler (void)
       Creates a scalar handler calling netsnmp_create_handler with a handler
       name defaulted to 'scalar' and access method,
       netsnmp_scalar_helper_handler. Parameters:
           void .RE

           Returns:
               Returns a pointer to a netsnmp_mib_handler struct which
               contains the handler's name and the access method

   int netsnmp_register_read_only_scalar (netsnmp_handler_registration *
       reginfo)
       This function registers a read only scalar helper handler. This
       function is very similar to netsnmp_register_scalar the only addition
       is that the 'read_only' handler is injected into the handler chain
       prior to injecting the serialize handler and registering reginfo.

       Parameters:
           reginfo a handler registration structure which could get created
           using netsnmp_create_handler_registration. Used to register a read
           only scalar helper handler.

       Returns:
           MIB_REGISTERED_OK is returned if the registration was a success.
           Failures are MIB_REGISTRATION_FAILURE and

   int netsnmp_register_scalar (netsnmp_handler_registration * reginfo)
       This function registers a scalar helper handler. The registered OID,
       reginfo->rootoid, space is extended for the instance subid using
       realloc() but the reginfo->rootoid_len length is not extended just yet.
       .This function subsequently injects the instance, scalar, and serialize
       helper handlers before actually registering reginfo.

       Each handler is injected/pushed to the top of the handler chain list
       and will be processed last in first out, LIFO.

       Parameters:
           reginfo a handler registration structure which could get created
           using netsnmp_create_handler_registration. Used to register a
           scalar helper handler.

       Returns:
           MIB_REGISTERED_OK is returned if the registration was a success.
           Failures are MIB_REGISTRATION_FAILURE and
           MIB_DUPLICATE_REGISTRATION.
