I am looking for a AMQP library, preferably written in C, that will work on a small embedded device. i.e. no OS and limited RAM and code size space (256k between both RAM and code).
I have seen the following post and number of others, I have looked into Qpid and RabbitMQ, but none seem suited to a small device.
Is there a AMQP implementation that has stable C++ Client library
Can anyone suggest a AMQP library that will work on a microcontroller? All functionality is not essential, even just support for telemetry would be good.
This seems to be an old question, but maybe this still helps.
Disclaimer: I am one of the authors of uamqp-c.
There are 2 choices I know of:
-Qpic Proton C: https://github.com/apache/qpid-proton
-uamqp-c: https://github.com/Azure/azure-uamqp-c
Cheers,

I am looking for a NIO type of library for C. I want to implement a multi threaded UDP network server that will have a lot of clients connecting to it.
Instead of attempting to code my own program to handle packets and 'connections'. I thought I would have a look if there is not already an existing library that has been tested and build for scalability and high performance.
I have found a few for Java but none for C. such as Apache Mina.
I am hoping that some one out there knows of a good one that may assist me.

It sounds like you want something to abstract select(), poll(), or whatever the most efficient mechanism is for your platform.
Have you looked at libevent and libev? There is a nice writeup here.
First of all, C has no classes. Secondly, C provides you with everything you need to implement a scalable and high performance solution. It's more low level than java's NIO, but there are good tutorials out there in google.
And if you want a library - try boosts' asio. It is C++, but perhaps you can use it.
If you are using Linux I strongly recommend you to use the POSIX API. It gives you resources for multithreading and networking acrosss any Linux box.
GNU C library
We are on designing a software in C(just C) need buffer structure in some part of that.
But I do know how to choose a good one?
Actually our program is open source and we need an open source and efficient buffer and queue library in C to implement this part.
Thanks for your helps.
you can use this container library :
https://github.com/jacob-navia/ccl
its from eccentric genius jacob navia (if you are not regular at comp.lang.c you will not understand it). But the thing is the library is quiet efficient and unusually "EXCELLENT" manual. The Documentation will surely buy c coders.
It has most common data structures like lists/queues/deques/circular linked lists etc/etc.
Consider using libevent. The newer version comes with a buffer interface suitable for the event framework that libevent provides. From their web page:
Libevent additionally provides a sophisticated framework for buffered network IO, with support for sockets, filters, rate-limiting, SSL, zero-copy file transmission, and IOCP. Libevent includes support for several useful protocols, including DNS, HTTP, and a minimal RPC framework.
I need to port a C library to Java so it can run on the Blackberry platform (mobile, native application). The options I am considering are:
bytecode conversion (cibyl, etc)
Complete port
Wrap C code around Java using JNA (would this even work for Blackberry?)
Please let me know which option is best. thanks
Aha. Some quick googling says "No, JNI does not work for blackberry" source:
http://supportforums.blackberry.com/t5/Java-Development/Can-we-use-JNI-Java-Native-Interface-approach-in-Blackberry/m-p/365362
http://supportforums.blackberry.com/t5/Java-Development/JNI/m-p/41140.
So you're stuck with bytecode conversion and complete port. Since I have no idea what bytecode conversion is, I'd go with a complete port, so long as you are familiar with both languages. If you can define bytecode conversion for me, I might be able to give you a better answer.
We also have an in-house developed C library for core functionality of our iOS and Android apps.
I asked about using cibyl to run this on BlackBerry in the form of a .jar and the good news is that it's possible: https://twitter.com/#!/simonkagstrom/status/114581622833152000 [backup of the tweet: "Sure, that's how #waze on the blackberry works."]
You can also try MoSync: http://twitter.com/#!/MoSync/status/115088826430533632 [backup of this one: "Yup, you can use MoSync for BB. There's "experimental" Blackberry support in MoSync 2.6, already used in live apps!"]
And David A Roberts, developer of LLJVM sent me this: "I'm not familiar with BlackBerry development, but I see no obvious reason why LLJVM wouldn't work, so long as the library doesn't rely too much on things like the C POSIX library (e.g. dirent.h, etc) - I
never got around to implementing this fully. Otherwise LLJVM would need to be updated suitably..."
Side note: BlackBerry's new Tablet OS and planned BBX phones actually have a native SDK but this QNX based stuff is quite unpopular. We just need to wait if BBX is going to become a success since Java based solutions are just too much risks.
I'd like to develop a network based application for the Arduino platform. The examples shipped with a Wi-Fi Shield library are all multifile sketches with a network part implemented in C. I'd like to figure out how to implement the network portion in a way regular C/C++ development is conducted (with a decent IDE and step-by-step debugger).
I noticed WiShield is build on top of the uIP library ((an open source full TCP/IP stack implementation for resource-constrained embedded devices)) and greatly influenced by it. Smart folks implemented DHCP and zero configuration implementations on top of it. How do people execute projects of such complexity and what tools are being used?
Are you looking for some Arduino emulator? I think these two should get you started.

Use the simple programming software that can easily work with arduino chips but don't make your project in complex situation putting some complex programs.
gcc 4.4.4 c89
Does any one know any sdp parses. That I can link to my application. Currently we are developing a SIP project. However, we need to parse the SDP for incoming/answering.
However, we don't have much time to implement. So just wondering if there are some simple ones out there they are easy and quick to work with.
Our application is written in c.
Many thanks for any advice,
Check out FreeSDP. But it is distributed under GPL
My company, RADVISION, offers a full commercial SIP stack written in C that includes an SDP parser. It might not be exactly what you're looking for, but it might reduce your development effort even further: http://www.radvision.com/Products/Developer/VoIP-Developer-Tools/SIP-Developer-Suite/
I haven't looked into open source stacks, but I would suspect that most SIP stacks would include an SDP parser. They are pretty closely tied together.
