mib2c has multiple configuration files depending on the type of
code you need to write. You must pick one depending on your need.
You requested mib2c to be run on the following part of the MIB tree:
  OID:                              vajTestObjects
  numeric translation:              .1.3.6.1.4.1.14327.38.38
  number of scalars within:         2
  number of tables within:          0
  number of notifications within:   0
First, do you want to generate code that is compatible with the
ucd-snmp 4.X line of code, or code for the newer Net-SNMP 5.X code
base (which provides a much greater choice of APIs to pick from):
  1) ucd-snmp style code
  2) Net-SNMP style code
Select your choice : 2 <Enter> (※)
**********************************************************************
GENERATING CODE FOR SCALAR OBJECTS:
**********************************************************************
  It looks like you have some scalars in the mib you requested, so I
  will now generate code for them if you wish. You have two choices
  for scalar API styles currently. Pick between them, or choose not
  to generate any code for the scalars:
  1) If you're writing code for some generic scalars
     (by hand use: "mib2c -c mib2c.scalar.conf vajTestObjects")
  2) If you want to magically "tie" integer variables to integer
     scalars
     (by hand use: "mib2c -c mib2c.int_watch.conf vajTestObjects")
  3) Don't generate any code for the scalars
Select your choice: 2 <Enter> (※)
      using the mib2c.int_watch.conf configuration file to generate your code.
*** Warning: only generating code for nodes of MIB type INTEGER

**********************************************************************
* NOTE WELL: The code generated by mib2c is only a template.  *YOU*  *
* must fill in the code before it'll work most of the time.  In many *
* cases, spots that MUST be edited within the files are marked with  *
* /* XXX */ or /* TODO */ comments.                                  *
