Thats why I said "in any case". Its better to have it now, since errors
causing data corruption are very hard to track.

Hm. I prefer to get things done with the system as much as possible without

the system libraries). If something can be done with a simple system call,
I don't see any reason to use a high level wrapper function to do the job.
