C++ binding for nanomsg

cppnanomsg: C++ binding for nanomsg library

To build:

1. git clone [email protected]:nanomsg/cppnanomsg.git
2. cd cppnanomsg
3. mkdir build
4. cd build
5. cmake ..
6. make
7. make test
8. sudo make install

Alternatively, given that the binding consists of a single header file, rather than installing it, you can avoid dependency and make nn.hpp part of your project.

cppnanomsg's Issues

The socket shutdown always gives EINVAL

Hi:
I am trying to make a proof-of-concept RPC with nanomsg and google protobuf.
The shutdown always gives EINVAL, what am I doing wrong ?

Example:
https://github.com/sroycode/nanorpc/blob/master/EchoClient.cc
line no 50 (commented out)

atcp.c abort on Windows Platform

My application is running on Windows Platform and Linux Platform at the same time with Pair Mode, the windows platform is running with bind and linux with connect. After few hours, the application running on Windows abort with this error : (Unexpected action: state=2 source=1 action=5 (e:\workspace\nanomsg-1.1.4\src\transports\tcp\atcp.c:228).

build cppnanomsg on win10-64,gcc has a problem

try to build cppnanomsg in win10-64 + codeblocks + cmake/win + mingw-gcc
from: https://nuwen.net/mingw.html
nanomsg itself built well.
cmake/win success, but when i try to build cppnanomsg i get: compiler problem:

#include <nanomsg/nn.h>
the file is in: C:\nanomsg-1.1.4\src

Exception thrown on recv if survey timed out

Submitting this as an issue, otherwise it gets lost on the mailinglist:
http://www.freelists.org/post/nanomsg/cppnanomsg-throws-on-recv-if-survey-timed-out

• recv throws except for EAGAIN
• should also allow error codes such as ETIMEDOUT, EFSM

The wrapper is not usable for the survey pattern, as it returns EFSM right now (should be ETIMEDOUT, see: nanomsg/nanomsg#194).

There's only a single exception type. Catching it on deadline expiration may also catch a fatal error.
There's no way to distinguish between them.

Tag releases of C++ bindings

Hi,

I think that it would be helpful to manage dependencies if we tag releases.

Cheers!
