* File: examples/cpp/inserters/example.cpp.inserter.xi/example.cpp.inserter.xi.cpp
|
|
*
|
|
* Purpose: C++ example program for Pantheios. Demonstrates:
|
|
*
|
|
* - use of Pantheios inserters for hex integral types
|
|
* - use of pantheios::logputs() in bail-out conditions
|
|
* - use of shorthand pan for namespace qualification
|
|
* - use of shorthand xi for hex integer inserter
|
