C++ alternative to perror()

Question

I know we can use

perror()

in C to print errors. I was just wondering if there is a C++ alternative to this, or whether I have to include

You could use the boost::system_error::error_code class.

#include 

#include 
#include 

void
PrintError(
        const std::string& message,
        int error
        )
{
    std::cerr << message << ": " <<
            boost::system::error_code(
                error,
                boost::system::get_system_category()
                ).message()
            << std::endl;
}

int
main()
{
    PrintError( "something went wrong!", EINVAL );
    return 0;
}

it's a tad verbose, and somewhat overkill if you aren't already using the boost_system library.
