How to convert an int to a string in DTrace?

Question

I'd like to be able to concatenate a string and an int using strjoin(), e.g.,

strjoin("ada", args[1]->unit_number);

but in order to do that I have to make sure that the int is first converted to a string.

I'm running DTrace on FreeBSD 13.1-RELEASE.

Answer 1

Apparently, there is an lltostr() that does that:

strjoin("ada", lltostr(args[1]->unit_number));
