I'm looking for a faster way to get more verbose information about
dtrace function arguments.
For example.
Say, I want to know more about the funciton
syscall:freebsd32:connect:return. I'd start off by doing a listing:
# dtrace -lvf connect
-----snip-------
43723 syscall freebsd32 connect return

Argument Types
args[0]: int
args[1]: caddr_t
args[2]: int
>From the output of the listing, I can see quite clearly there are
three arguments for this function - int, caddr_t, int; but I can't see
from this output what these refer to.
I could probably find the answer by digging through header files and
source code, but this isn't exactly efficient. Is there an easier way
to find more information about functions (not specifically this one)?
