Extensible error reporting.
This Release
Dependencies
Boost.System
The Boost.System library, part of Boost C++ Libraries,
implements an extensible framework for error reporting in the form of an
error_code class and supporting facilities.
It has been proposed for the C++11 standard, has been accepted, and
is now available as part of the standard library in the <system_error>
header. However, the Boost implementation has continued to evolve and
gain enhancements and additional functionality, such as support for
attaching source locations
to error_code, and a result<T> class that can carry either a value
or an error code.
See the documentation of System for more information.
Since <system_error> is a relatively undocumented portion of the C++
standard library, the documentation of Boost.System may be useful to you
even if you use the standard components.
