I wondered why this is type 'char *', when we can use 'int' as usual and
have '**result' (same as monitor command does).
It depends on generating the code automatically Eric suggested.
It decides the returning type.

It is my mistake.

Shouldn't this be allowed only for read-only connections?

You have 'domain->conn' in 'conn' already.
