Is it possible to use DTrace to display the number of arguments and their types 
for userland or kernel functions that are not explicitly instrumented or 
documented by their authors?  We're talking about functions provided by Veritas 
VxVM/VxFS and the like, and for example, we might want to try tracing I/Os from 
App => VxFS => VxVM => ssd driver to see where I/Os get aggregated or broken 
up.  But without being able to determine function signatures, it will be very 
hard to even begin such a process.

It would seem that this is possible, but I haven't seen any examples of such a 
use.  I'm presuming that this would be done via fbt.
