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