snprintf()

Now I know that

       The  functions  snprintf()  and  vsnprintf()  do  not write more than size bytes (including the terminating null byte ('\0')). If the output was truncated due to this limit then the return value is the number of characters (excluding the terminating null byte) which would have been written to the final string if  enough space had been available. Thus, a return value of size or more means that the output was truncated.

LinuxFr.org: Interview with Andrew Tanenbaum

Andrew Tanenbaum on Linux, GPL and stuff

LinuxFr.org : Do you think the Linux success is a proof he was right
or is it unrelated?

Andrew Tanenbaum : No, Linux "succeeded" because BSD was frozen out of
the market by AT&T at a crucial time. That's just dumb luck. Also, success
is relative. I run a political website that ordinary people read. On that
site statistics show that about 5% is Linux, 30% is Macintosh (which is BSD
inside) and the rest is Windows. These are ordinary people, not computer
geeks. I don't think of 5% as that big a success story.
