// NAME
//   DemoTokenStandalone.c
//
// DESCRIPTION
//   This Demo file shows standalone connection using token based authentication
//   to Oracle Autonomous Database from Oracle Compute Infrastructure.
//
// PREQUISITES
//   - Oracle Client libraries 19.14 (or later), or 21.5 (or later).
//
//   - The Oracle Cloud Infrastructure command line interface (OCI-CLI).  The
//     command line interface (CLI) is a tool that enables you to work with
//     Oracle Cloud Infrastructure objects and services at a command line, see
//     https://docs.oracle.com/en-us/iaas/Content/API/Concepts/cliconcepts.htm
//
//   - Set these environment variables (see the code explanation):
//      ODPIC_SAMPLES_ACCESS_TOKEN_LOC
//      ODPIC_SAMPLES_CONNECT_STRING
