ftruncate fails with files larger >= 2GB because off_t gets interpreted as
32 bit signed integer...
I can find some archived cygwin messages referencing bug fixes to
ftruncate64 in the cygwin.dll. However, using ftruncate64 results in an
unresolved symbol.
In fact
Greetings.
I am trying to write a program using cygwin that truncates files larger than
4GB to a specific size as part of its functionality.
However, I cannot find a ftruncate64() in the cygwin libraries. Are there
other alternatives available?
BTW. Normally I would search the cygwin archives f

I didn't think of using Google. It doesn't help much, because the search

I stand correct. The bug was elsewhere in my code. I have been working
with java so
less than 16 terabytes as a maximum size on
a partition that only has 7 gigabytes of space available.

OK. Then there must be a problem in the way cygwin creates sparse files,
since the files created by seeking past the end in cygwin always take up the
full amount of disk space. I've verified this with both Windows and cygwin
tools. I'll try taking it up on the cygwin list to see what I can learn

When you create this as a service, use the SIGINT as the termination

I believe I posted a script in the past, that I used to work around this
problem.
Basically the problem is that the runlevels never get set. So you need a
script that manually steps through and sets each of the runlevels in the
correct order. Overall it is a huge pain. After several generations

Hmmm. I forgot one other advantage of symbolic links. They are independent
of the locations of each other. i.e.
touch /tmp/foo.txt
ln /tmp/foo.txt /home/bcr/foo.txt
mkdir /home/bcr/tmp
mv /tmp/foo.txt /home/bcr/tmp/foo.txt
Both versions of foo.txt are still valid, even though they woul
One obvious thing hard links allow is a way to have the same file with
different permissions. With a symbolic link you need both access
permissions for the symbolic link and actual file. i.e.
ln -s /tmp/foo.exe /home/bcr/foo.exe
chmod ugo-x /tmp/foo.exe
chmod ugo+x /home/bcr/foo.exe

Not necessarily. Not every application is designed to work across different

Quite simple. When you run "ssh" it ca

I found I had to write a custom /usr/sbin/init.sh script to get init to work

Check the permissions on your directories. 'ssh' will ignore a .ssh

i.e. Both /home and /home/.ssh should have permissions 755 or something even
