 recInfo()
 Retrieve the information about a row
------------------------------------------------------------------------------
 Prototype

     ERRCODE recInfo(
                          AREAP wa,
                          ITEM itmRecID,
                          USHORT uiInfoType,
                          ITEM itmInfo
                       )

 Arguments

     wa is a pointer to self.

     itmRecID is a pointer to an item that determines the current row
     identifier and will normally be a number indicating the row number.

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

     itmInfo is a pointer to a CA-Clipper item which will contain the
     required information.  The data type of itmInfo depends on the value of
     uiInfoType.

 Description

     recInfo() retrieves information about the state of a record
     (row).  The information requested is defined by the value passed in
     uiInfoType.  The record information that is available is defined by the
     RDD.  Some suggested values for uiInfoType (constants with "DBRI_"
     prefix) and their associated meanings are provided in the header file
     Rdd.api.

 Default Behavior

     recInfo() is used to implement the DBRecInfo() function and
     is called any time information about the row is needed to perform an
     operation.  In the default implementation there are five properties
     (shown in the following table) defined for each row (the constants are
     defined in Rdd.api).

     recInfo() Information types
     ------------------------------------------------------------------------
     Constant        Meaning
     ------------------------------------------------------------------------
     DBRI_DELETED    Check the 'deleted' status of the row
     DBRI_LOCKED     Check if the row is locked
     DBRI_RECNO      Get the row position number
     DBRI_RECSIZE    Get the record size
     DBRI_UPDATED    Check if the row was updated
     ------------------------------------------------------------------------

     Warning!  itmInfo must be a valid item.

 Implementation Notes

     .  You must implement new behavior for this method only if your
        driver requires properties in addition to those listed in
        the previous table.

     .  If your implementation of recInfo() cannot determine the
        return value based on the value of uiInfoType, you should allow the
        work area default implementation to attempt it by calling
        SUPER_RECINFO().

     .  If itmInfo contains a value other than NIL, it is the new
        value for the property.  If your implementation warrants, you can
        change itmInfo by assigning the new value to it.

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