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