💅 ZMQ_TERM(3) — the 0MQ Manual, but make it make sense

okay so bestie, we're in the 0MQ Manual today and this page is all about zmq_term — the terminate the 0MQ context girlie. she's giving "shutting down the whole group chat" energy 🫶

✨ SYNOPSIS ✨

int zmq_term (void *context);

that's it. that's the whole vibe check. one function, one pointer, one big goodbye 👋

🌸 DESCRIPTION 🌸

so like — the zmq_term() function shall terminate the 0MQ context context. like, fr fr, it ends it. no cap.

context termination is a whole ✨process✨ and it happens in these steps, okay, don't skip ahead:

  1. any blocking operations that are currently in progress on sockets open within context shall return immediately with an error code of ETERM. and with the exception of zmq_close(), any further operations on sockets open within context shall fail with an error code of ETERM. so basically everything gets the ETERM treatment except zmq_close() — she's the exception, she's the main character 💅
  2. after interrupting all those blocking calls, zmq_term() shall block until the following conditions are satisfied:
    • all sockets open within context have been closed with zmq_close() 🔒
    • for each socket within context, all messages sent by the application with zmq_send() have either been physically transferred to a network peer, or the socket's linger period set with the ZMQ_LINGER socket option has expired ⏳

lowkey important: for further details regarding socket linger behaviour, refer to the ZMQ_LINGER option in zmq_setsockopt(3). she knows things. go read her.

🚨 and bestie, heads up: this function is deprecated by zmq_ctx_term(3). it's giving "old icon, still iconic, but use the new one" — so like, keep that in mind. periodt.

👑 RETURN VALUE 👑

zmq_term() shall return zero if successful. slay. ✨

otherwise it shall return -1 and set errno to one of the values defined below. not slay. 😭

💀 ERRORS 💀

  • EFAULT — the provided context was invalid. like, it wasn't even a thing. invalid vibes entirely 🙈
  • EINTR — termination was interrupted by a signal. it can be restarted if needed, so like, no biggie, just try again 🫶
