Detailed Description

Class providing formatted output.

Beside a set of print() functions, this class also supports a collection of format configuration classes:

• elm::io::IntFormat
• elm::io;;FloatFormat
• elm::io::StringFormat

Below is an example of the use of these classes:

void *p;
cout << "pointer = " << io::fmt(t::uint64(p)).right().pad('0').width(32) << io::endl;

Additionally, this class provides simple facilities to output to a file and to manage release of created streams.
