 info()
 Retrieve information about the current driver
------------------------------------------------------------------------------
 Prototype

     ERRCODE info(
                   WORKAREAP wa,
                   USHORT message,
                   ITEM value
                 )

 Arguments

     wa is a pointer to self.

     message is a value that determines the type of information to be
     provided.

     value is a CA-Clipper Item which will contain the information that
     corresponds to message.

 Description

     Obtains information regarding the current driver.

 Default Behavior

     The info() method returns Items of data in response to some basic
     questions concerning the driver's functionality.  Those questions
     are defined by value passed in message.  Some suggested values for
     message and their associated meanings are provided in the header
     file Rdd.api.

     Warning!  value must be a valid Item.

 Implementation Notes

     .  If your implementation of info() cannot determine the return
        value based on the value of message, you should allow the workarea
        default implementation to attempt it by calling SUPERINFO().

     .  The first 1000 possible values for message are reserved by
        CA-Clipper.
