MQTTSubscribeOpts.h(3)

💖 MQTTSubscribeOpts.h — the header that's giving "subscribe options, but make it V5" 💖

okay bestie, sit down, hydrate, and let's talk about MQTTSubscribeOpts.h, a whole header file from the Library Functions Manual. she's short, she's sweet, and she's carrying the MQTT V5 subscribe options on her back like the icon she is. no cap.

---

🌸 NAME 🌸

MQTTSubscribeOpts.h — literally just the name, the whole thing, the moment 💅

---

✨ SYNOPSIS ✨

here's the tea, laid out exactly how the source says it:

🎀 Data Structures

• struct MQTTSubscribe_options — yeah. that's the one. the whole squad is in there 🫶

🦋 Macros

#define MQTTSubscribe_options_initializer   { {'M', 'Q', 'S', 'O'}, 0,
    0, 0, 0 }

💜 Typedefs

typedef struct MQTTSubscribe_options MQTTSubscribe_options

---

👑 Macro Definition Documentation 👑

#define MQTTSubscribe_options_initializer { {'M', 'Q', 'S', 'O'}, 0, 0, 0, 0 }

this macro is lowkey the glow-up starter pack — one magic initializer and your options are ready to go. she spells out 'M', 'Q', 'S', 'O' at the front and then fills the rest with zeros, and yes, that is exactly four zeros after the braces, character for character, don't @ me. ✨

---

🌈 Typedef Documentation 🌈

typedef struct MQTTSubscribe_options MQTTSubscribe_options

the description, direct from the source: The MQTT V5 subscribe options, apart from QoS which existed before V5.

so like — everything V5 brought to the subscribe table except QoS, because QoS was already here before V5, she's a legacy queen and we respect her. periodt. 💅

no warnings here bestie, no deprecated nonsense, no undefined behaviour, just a tidy little header doing her job. vibe check: passed. ✅
