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
header. However, the Boost implementation has continued to evolve and
gain enhancements and additional functionality, such as support for
attaching source locations
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.
<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.
