   4  * sqltypes.h
   5  *
   6  * This is the lowest level include in unixODBC. It defines
   7  * the basic types required by unixODBC and is heavily based
   8  * upon the MS include of the same name (it has to be for
   9  * binary compatability between drivers developed under different
  10  * packages).
  11  *
  12  * You can include this file directly but it is almost always
  13  * included indirectly, by including.. for example sqlext.h
  14  *
  15  * This include makes no effort to be usefull on any platforms other
  16  * than Linux (with some exceptions for UNIX in general).
  17  *
  18  * !!!DO NOT CONTAMINATE THIS FILE WITH NON-Linux CODE!!!
