Quick question:
Is there a Tcl command that is equivalent to the unix fsync() system
call? That is, a call that blocks until a given file is actually
written to disk? Note that I'm not talking about flush, which moves
data from user space to kernel space but a call that guarantees that
the data went to the disk and the disk said that it's on the platter.
Thanks,
Zoltan

Not in the base Tcl distribution.

The TclX extension, however, does have a 'sync' command that makes the
appropriate kernel call:
http://wiki.tcl.tk/2053
Whether your kernel, filesystem, and disk hardware tell the truth is
beyond both Tcl's and TclX's control.

That's what I need, thanks a lot!

drives do actually tell the truth. On the other hand, USB sticks seem
to be compulsory liars. It was a few years back, so things might have
changed, though.
Thanks again!
