zmq_proxy incorrect declaration

[ADDubovik]

zmq_proxy declaration is incompatible with original declaration (there's should be "const" added).

[sigiesec]

I am not sure what you mean, where is the incompatible declaration and where is the original?

[ADDubovik]

http://api.zeromq.org/4-2:zmq-proxy :
int zmq_proxy (const void *frontend, const void *backend, const void *capture);

ZMQ.h :
ZMQ_EXPORT int zmq_proxy (void *frontend_, void *backend_, void *capture_);

@sigiesec I believe this is about arguments' constness.

• libzmq:
  int zmq_proxy (const void *frontend, const void *backend, const void *capture);
• cppzmq has no const arguments:
  inline void proxy(void *frontend, void *backend, void *capture)

Hm, the libzmq documentation is wrong, the arguments are not declared const in zmq.h:
https://github.com/zeromq/libzmq/blob/f21bae529e7e62ab51c97375681db89de055c3ed/include/zmq.h#L525

[ADDubovik]

Oh, really.
Should I create an issue in libzmq?

[sigiesec]

I fixed the documentation: zeromq/libzmq#3422

[sigiesec]

I think this issue can the be closed, right?

[ADDubovik]

There's also erraneous WEB-documentation (http://api.zeromq.org/4-2:zmq-proxy).

I don't know if libzmq 4.2.x is still maintained. With the next libzmq release, new 4.3 docs will probably be generated by the maintainers. But this isn't a cppzmq issue.
