Demonstrates the use of Pantheios to log binary regions in a C++ program in a Base 64 format, using the pantheios::b64 inserter.

Note:

To use the pantheios::b64 inserter you must have downloaded, built and installed the Synesis Software b64 library, and compile and link in the Pantheios source file src/inserters/b64.cpp.

 * Purpose:     C++ example program for Pantheios. Demonstrates:
 *
 *                - use of Pantheios b64 inserter for blob types
 *                - use of pantheios::logputs() in bail-out conditions
