Re: [fuse-devel] Using negative_timeout through the lowlevel interface.

[Paul N. <pa...@ps...>]

Hi Miklos,
I did see this particular tidbit regarding the use of ino #0.  What is 
not clear to me is how to set the timeout via the lowlevel interface.  I 
suppose what I'm after is the sanctioned method for modifying struct 
fuse_config members when using lowlevel.
thanks,
Paul
