Fastio try except

Is there any need for us to worry about accessing fastio
parameters within try/except. Does the I/O manager
probes the validity of the arguments (using its
own try/except block)

No. With FastIo - no at all. Do the validation yourself or just avoid using FastIo.

Maxim’s response was not all that clear so I want to clarify.

The answer is yes, you must worry about using a try/except around buffers in fastio operations. In fact, all buffers in all fastio operations must be treated as method-neither buffers, even when the associated IRP operation functions differently.
