Re: [zeromq-dev] czmq: Error Traceability with assert(...) and release code

assert() gives you a core dump that has complete context, including stack trace. How do you propose to provide the same, if you replace assert with return? On 11/03/2014 12:10 AM, "Christoph Zach" wrote: > On Monday 10 March 2014 10:36:22 Pieter Hintjens wrote: > > This theory is fine in theory.

Re: [zeromq-dev] Need 100K+ IPC sockets

Correct me if I'm wrong here, but I suspect you can't create more than 64K of ZeroMQ sockets on a single non-Linux box just because every ZeroMQ socket has a socketpair, which occupies one ephemeral port. Total number ports is limited to 64K on any single box. On Linux ZeroMQ uses eventfd instead

Besides the zeromq usage issue(s), you have charset encoding mismatch. outData.getBytes() returns your string in UTF-16 encoding. When you receive this byte buffer in your CPP server, you just pass it to constructor of std::string that accepts it until the first 0 byte. In case of latin text encod
