Package: libstdc++6
Version: 4.0.2-5
Severity: normal
Using libstdc++, I've got code like this:
__gnu_cxx::stdio_filebuf<char> fdbuf(fd, std::ios::in);
The doxygen docs for this fd ctor say "The file descriptor will be
automatically closed when the stdio_filebuf is closed/destroyed.", but I
appear to be leaking fds due to making the assumption I was passing
ownership of the fd to this streambuf, and not closing it by hand.
Is this a documentation bug?
I've checked <ext/stdio_filebuf.h>, and I can't see any referece to
close(). The docs for the FILE* ctor say " The FILE* will **not** be
automatically closed when the stdio_filebuf is closed/destroyed.", so it
looks like the docs are wrong in this case.
If this is true, just adding "not" should fix it:
