File descriptors 0, 1, and 2 are respectively: standard input, standard output,
and standard error.
Programs generally tend to exit without closing them, so it's natural that they
would still be open at exit, as Valgrind diagnoses.
I'm guessing it's telling you that because of the --track-fds=yes option you
used, or else because of the verbose (-v) option.

Subject: [Valgrind-users] Understanding open file descriptor at exit
Hello,
When I ran valgrind, I got the following message, which I'm having trouble
understand.
==21285== FILE DESCRIPTORS: 3 open at exit.
==21285== Open file descriptor 2: /dev/pts/1
==21285== <inherited from parent>
==21285==
==21285== Open file descriptor 1: /dev/pts/1
==21285== <inherited from parent>
==21285==
==21285== Open file descriptor 0: /dev/pts/1
==21285== <inherited from parent>
Isn't /dev/pts/1 my terminal?
I don't know if matters for this question, but I used the following options for
valgrind:
--tool=memcheck --leak-check=full --show-reachable=yes --num-callers=20
--track-fds=yes -v
Thank you,
Martin
