Exception occurs in two cases: 1. Widechar representation of domain name is too long and not fit multibyte buffer after conversion; 2. Domain name contains resolve error message. I think it makes sense to use the _TRUNCATE constant https://learn.microsoft.com/en-us/cpp/c-runtime-library/truncate?view=msvc-170 https://learn.microsoft.com/en-us/cpp/c-runtime-library/reference/wcstombs-s-wcstombs-s-l?view=msvc-170
