Printing wide character strings (gdb->General)

gdb won't by default let you print wide character strings. Here is a little bit of gdb code that'll let you print them. In case that page moves, here is the relevant stuff. Paste this into your .gdbinit and then you can use wchar_print:

define wchar_print
        echo "

        set $i = 0
        while (1 == 1)
                set $c = (char)(($arg0)[$i++])
                if ($c == '\0')
                        loop_break
                end
                printf "%c", $c
        end

        echo "

end

document wchar_print
wchar_print <wstr>
Print ASCII part of <wstr>, which is a wide character string of type wchar_t*.
end
