+ * Header file of Pure API function declarations.
+ *
+ * Explicitly no copyright.
+ * You may recompile and redistribute these definitions as required.
+ *
+ * NOTE1: In some situations when compiling with MFC, you should
+ *        enable the setting 'Not using precompiled headers' in Visual C++
+ *        to avoid a compiler diagnostic.
+ *
+ * NOTE2: This file works through the use of deep magic.  Calls to functions
+ *        in this file are replaced with calls into the OCI runtime system
+ *        when an instrumented version of this program is run.
+ *
+ * NOTE3: The static vars avoidGy_n (where n is a unique number) are used
+ *        to prevent optimizing the functions away when compiler option
+ *        /Gy is set. This is needed so that NOTE2 works properly.
