Yup, that will do. But, still I wonder why the typecast fails ?
Because the argument is an integer, not a pointer to a kernel string?
Typecasting in D is like typecasting in C: almost no work is done.
Certainly no lookup of the file descriptor table is done.

Subject: Re: [dtrace-discuss] Convert fd into string
Why not just aggregate on the tuple <fd, file name>? Something like
this:
syscall::read:entry
{
@c[arg0, fds[arg0].fi_pathname] = count(); }
If the output's unsatisfactory, you could always use a printa() in
en
END clause to get it into the format you want.

I just need to print the file descriptor number as a string. I
would like to join fd and file name into one string and then
aggregate on reads/writes reason I want to do this is, for sockets
fi_pathname just shows up as "unknown" - instead if I can get fd, I
can do pfiles and get the socket details ..
