Suppress stdout from shared libraries

[Frederick Gotham]

Hi guys, I've been meditating for about 8 years now, averaging about 30
hours per month (typically 1 hour per day).

I don't typically get headaches, it hasn't ever been a real problem for
me.

This past week or so I've made a lot of progress in dealing with a
bereavement and continuing on with my life. With this progress has come
irritability, agitation, tiredness, sleepless nights, and headaches. I'm
also craving alcohol and cigarettes which I haven't had in years. The
headaches are almost daily now.

Of course there can always be a medical reason for a headache, but I'm
satisfied to assert that what I'm experiencing right now is a part of
the process of emotional restoration (some years after an emotional
upheaval). I don't particularly like sleepless nights and headaches,
however I'm willing to tolerate this right now. But of course everyone
has their limit.

As I'm working from home and spending 8 hours a day doing technical work,
my headaches really aren't helping. The frame of mind I'm in later in
the day also probably isn't pleasant to others around me after I've been
tolerating a headache all day.

Today I've taken two over-the-counter non-drousy medications: 2 pills of
paracetamol and 2 pills of ibuprofen. Lately I've had to do this approx.
1 out of every 3 days otherwise I start being really short-tempered and
nastily impatient with people later in the day. I'm hoping this fizzles
out sooner rather than later.

================
Do you guys think I should just do away with the pills and just have a
headaches for a few days? I do understand the headaches and sleepless
night are a necessary part of emotional restoration, but would I just be
torturing myself to endure it without the occasional ibuprofen?

-====================

I'm in my 30's now and I've had a few different reputations in my life,
on three continents.

I've been to both extremes -- I've been viewed as weak and vulnerable
and an easy target, and I've also been viewed as a psycho you don't want
to walk within 10 feet of.

In the "setup_worksation.sh" file for the ProGen4 dev branch, the key
server is set as 10.160.98.89. I am able to ping this address at the
command line:

PING 10.160.98.89 (10.160.98.89) 56(84) bytes of data.
64 bytes from 10.160.98.89: icmp_seq=1 ttl=60 time=150 ms
64 bytes from 10.160.98.89: icmp_seq=2 ttl=60 time=157 ms

When I run "setup_workstation.sh pg4 amb_cv22_evk armR
cv22_illustra_ptz", I can see:

connect 10.160.98.89:9022
new ssl

However, further down it says this:
Trying to connect to Ambarella key server...
Trying to connect to Ambarella key server...
Trying to connect to Ambarella key server...
Failed to start Ambarella dev daemon. SDK build will not be successful

This means that I can't get a local build. Anyone know what's wrong?

===========================

I can't speak for the other five recipients of your email, David, but
personally speaking no apology is necessary. We are a team of skilled
professionals employed to develop saleable products, and we are assigned
specific individual tasks by our superiors. Your interest in the current
task, or any other member of the Illustra team's interest in the current
task (myself included), isn't of concern. We get paid to do this stuff --
interested or not.

Do I understand correctly that you're no longer willing to collaborate
with your team members on the topic of Audio Out? If so, I would direct
you toward your superiors rather than discussing this boggle with
colleagues, as I do not have the authority to assign or de-assign your
work tasks.

Speaking soley for myself, I will continue on the task I was assigned
and I will collaborate and cooperate with my fellow team members and
superiors.

I'm writing a program that links with a handful of shared libraries.
Some of the shared libraries write the occassional infrequent message to
stdout.

I want to suppress the messages outputted from these shared libraries,
namely from statements such as the following:

cout << "whatever" << some_number << endl;
printf("whatever%i\n", some_number);

However I want my own program to still be able to use "cout" to print to
stdout. (I don't have any use for "printf" or any related C-style IO
functions in my pgrogram).

So the first thing I've done is allocated static duration memory for an
'ostream' object. My object is called "g_exclusive_cout":

std::aligned_union<0, std::ostream>::type g_exclusive_cout;

My program is for Linux and so I've started by coding a Linux-specific
solution, however I'm curious as to whether there's a C++11 ANSI/ISO
portable solution.

Next I call the following function when the program starts:

void Suppress_Cout_From_Shared_Libraries(void)
{
fflush(stdout);

static __gnu_cxx::stdio_filebuf<char>
filebuf(dup(fileno(stdout)), std::ios::out);

freopen("/dev/null", "w", stdout);

::new(&g_exclusive_cout) std::ostream(&filebuf);
}


And then lastly I have a macro for exclusive cout, "excout":

#define excout ( \
*static_cast<std::ostream*>( \
static_cast<void*>(&g_exclusive_cout) \
) \
)

And so then in my own program, I always use "excout" instead of "cout",
for example:

int main(void)
{
Suppress_Cout_From_Shared_Libraries();

excout << "Hello World!" << endl;
}

This solution works for me. Of course I've used POSIX-specific functions
and GNU compiler extensions to pull it off. I wonder if there's an
ANSI/ISO C++11 way of doing it? By the way, since multithreading was
introduced into C++11, there is a gaurantee that calls to "cout <<
whatever" are thread-safe. I wonder if my own code with "excout" is
thread-safe, or whether I'll have to wrap methods called on "excout"
within a mutex?

I'm trying to use a very old newsreader under Wine on Linux, it's called
"Xnews", and it just posted a load of garbage copy-pasted from another
window.

Suppress stdout from shared libraries".
