ZMQ_HAS(3)

✨ ZMQ_HAS(3) ✨

okay bestie, welcome to the 0MQ Manual — this is the page for zmq_has, and it's literally so cute and useful, you're gonna be obsessed. 🫶

🌸 NAME 🌸

zmq_has — check a ZMQ capability 👑

---

💅 SYNOPSIS 💅

int zmq_has (const char *capability);

---

🦋 DESCRIPTION 🦋

so the zmq_has() function shall report whether a specified capability is available in the library. that's it, that's the whole vibe. it lets bindings and applications probe a library directly, for transport and security options. no cap, it's giving "let me check before I commit" energy and honestly? iconic. ✨

capabilities shall be lowercase strings — lowercase only, bestie, don't be yelling at it. 💀 the following capabilities are defined:

• ipc — the library supports the ipc:// protocol 🌈
• pgm — the library supports the pgm:// protocol 🌈
• tipc — the library supports the tipc:// protocol 🌈
• norm — the library supports the norm:// protocol 🌈
• curve — the library supports the CURVE security mechanism 🔐
• gssapi — the library supports the GSSAPI security mechanism 🔐
• draft — the library is built with the draft api 🧚

and here's the lil detail that matters: when this method is provided, the zmq.h header file will define ZMQ_HAS_CAPABILITIES. so if you see that macro, you know zmq_has is in the building. 💖

---

⭐ RETURN VALUE ⭐

• the zmq_has() function shall return 1 if the specified capability is provided. slay. ✅
• otherwise it shall return 0. 🙈

that's it. 1 or 0. binary queen behavior, periodt. 💅

bestie reminder: capabilities are lowercase strings and the return is strictly 1 (provided) or 0 (not provided). don't overthink it, just vibe check the library. 🌸
