Use std::system_error

[Eyal Rozenberg]

C++ has had, for the last 10 years, a standard, cross-platform mechanism for representing system errors: <system_error>. I believe you should use it instead of your own custom exceptions.

See also:

<system_error> categories and standard/system error codes

on StackOverflow.
