cpp/example_cpp_b64/example_cpp_b64.cpp

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

Note:

To use the pantheios::b64 inserter class 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.

 *                - use of Pantheios b64 inserter for blob types
 *                - use of pantheios::puts() in bail-out conditions
