 * Chapter 12, Oracle10g PL/SQL Programming
 * by Ron Hardman, Michael McLaughlin and Scott Urman
 *
 * This script opens a file and write a single line
 * of text to the file. It is used in conjunction
 * with the create_library2.sql script.
 *
 * Compilation instructions are below. You need to have
 * a C compiler installed on your local platform. If
 * you do not have a C compiler this is not possible.
 * You do the following:
 *  - You need to compile this as a shared library in
 *    UNIX, which has an *.so extension and as a
 *    Dynamic Link Library (*.DLL) on the Windows
 *    platforms.
 *  - On UNIX, there are two different ways to compile
 *    a shared library. They are noted below for
 *    reference:
 *    - Solaris: gcc -G -o sample.so sample.c
 *    - GNU:     gcc -shared -o sample.so sample.c
 *  - It is assumed Microsoft's IDE is well designed
 *    and provides help messages to compile a DLL.
