You can easily create a deeply nested directory whose absolute
file name
is longer than MAXPATHLEN. The MAXPATHLEN (a.k.a PATH_MAX)
parameter only
limits the length of the file name that can be passed to system
calls, but
has no connection to maximum length of an (absoulte) file name in
a system
(you can create virtually infinite long file names on Linux, for
example).
But in this case, the file name we are talking about was _produced_ by
a function, i.e. by some system call. I don't think such a file name
can exceed the syscall limits, can it?
Well, if you have a directory on one filesystem with MAXPATHLEN and
then mount another filesystem under that directory, that would make
all paths in the mounted file system exceed MAXPATHLEN. In theory at
least, I haven't tried it.
