Re: IFS - stat() & opendir()

[Scott Klement <klemscot@xxxxxxxxxxxx>]

Yes, you should do a closedir() for each opendir() that you do.   In UNIX
(which these APIs are intented to emulate) directories are nothing but
specially formatted files.   When you do an opendir() you are opening that
file.   readdir() reads through it's contents, and closedir() will close
it when you're done with it...   it's no different from any other file.

It shouldn't matter if you do the stat() before or after calling
closedir(), since programs can have multiple files open at the same
time...   just use caution that you do, in fact, close them at some point
so you don't start amassing large numbers of open files...

That's my guess as to why you'd get a "maximum number of files open"..
because you're opening directories or other files and not closing them...
probably in a loop or recursive procedure...
