[Tech] ClientGet questions

[Juergen Urner]

Hello,

I am playing a bit around with the client protocol (2.0)
currently and a have few questions.

One is regarding 'ClientGet'. To download a file to disk I have
to pass the filepath and its size in the request. This is leaving me
with one or the other headscratch. How am I supposed to know
in advance what type of file I am requesting and what its size
is?

One of the (bit hackish) solutions I came up with  sending a 'ClientGet'
with a size of -1 or 0, hoping the request fails, to get the missing 
peaces from 
'GetFailed'  (code 21), but have no idea if this is intendet use or how 
reliable it is.

Another headscratch is: how am I supposed to know in advance if a filepath
I pass today can be written tommorow? In the meantime some other file 
with the same
name may find its way into the folder, the folder might disappear... or 
whatever.
So I wonder why the filepath (and TestDDA) is not requested somewhere 
near 'DataFound',
when it is actually needed.

Anyone any hints?



Thanks, Juergen
