Re: [zeromq-dev] Call for testing for libzmq 4.2.3

2017-11-24 Thread Francesco
Hi Luca,
I investigated a little more this issue today and I spotted that it was a
false alarm.
Long story short: for several reasons I need to store shared libraries in a
specific place (not inside Linux standard folders); to ensure my binaries
can find the shared libraries I inject into libzmq the GCC -Xlinker -rpath
/my/path option. The result is that regardless of libtool automagic
LD_LIBRARY_PATH adjustments the tests were running against the outdated
libzmq version inside /my/path. After updating /my/path/libzmq.so.5.1.3 the
tests pass just fine, included test_req_relaxed.

I will start testing libzmq in my company's bigger software next week and
will let you know...

Thanks,
Francesco

Re: [zeromq-dev] How to receive byte array in ZeroMQ C++

2017-11-24 Thread Ravi Joshi via zeromq-dev
Thanks Ju.

Actually, I was confused a litle. I saw the C API, which uses zmsg_popmsg. 
However, since I am using C++, I tried to search for equivalent C++ API but I 
couldn't.

This is why I mentioned twice that the message consists of ZFrame and ZFrame is 
initialized with the byte array. Hence I was expecting that first I need to use 
some kind of pop msg and then get the byte array.

I really appreciate your help.

Thanks again.

In C bindings you need to "pop" each part of the message in a variable 

of your choice, then you can handle that variable as you do normal in 

your language.

In C after receiving the message from your socket,

you do :

int msgsize =zmsg_size(receivedMessage);

byte *msgContent =zmsg_popmsg(receivedMessage);


then 


for (int x = 0; i <  msgsize; i++) {
doSomeThingWith(msgContent[i]);
}

Hello Ravi,


If that's just a raw byte array, msg.data() should to the trick. For 
example:

for (size_t i = 0; i < msg.size(); ++i) {

}

Hello Ravi,


If that's just a raw byte array, msg.data() should to the trick. For 
example:

for (size_t i = 0; i < msg.size(); ++i) {
printf("%02X ", msg.data()[i]);
}


Regards,
Mykola
