fieldCount()
 Determine the number of columns (fields) in the work area
------------------------------------------------------------------------------
 Prototype

     ERRCODE fieldCount(
                             AREAP wa,
                             USHORTP fieldCount
                           )

 Arguments

     wa is a pointer to self.

     fieldCount is a pointer to an unsigned short integer value that
     specifies the number of columns in the work area.

 Description

     fieldCount() gets the physical column count for wa.

 Default Behavior

     Copies wa->uiFieldCount into fieldCount.

 Implementation Notes

     .  If the number of columns is dynamic, fieldCount() should
        return the count for the current row (record).

     Warning!  fieldCount must point to sizeof(USHORT) bytes of allocated
     memory.
