MQTTClient_init_options(3)

💖 MQTTClient_init_options — bestie's guide to the init options struct 💖

okay so this is a page from the Library Functions Manual (yes, section 3, the library-functions girlies) and it's all about MQTTClient_init_options, a lil struct you use to tell the library how you wanna get set up. she's small, she's simple, she's giving "three fields and a dream". let's get into it ✨

---

🌸 NAME 🌸

MQTTClient_init_options — the initialization options struct, no cap 🫶

---

✨ SYNOPSIS ✨

#include <MQTTClient.h>

🎀 Data Fields

char struct_id [4]
int  struct_version
int  do_openssl_init

---

🦋 DETAILED DESCRIPTION 🦋

Initialization options. that's literally the whole vibe. this struct is the little starter pack of settings you hand over when things are getting initialized. periodt 💅

---

💜 FIELD DOCUMENTATION 💜

char struct_id[4]

the eyecatcher for this structure. must be MQTG. like, it's the secret handshake — if it doesn't say MQTG, it's not the right struct, bestie, don't even try it 🙈

int struct_version

the version number of this structure. must be 0. that's it. that's the number. zero. don't be out here freestyling 🌈

int do_openssl_init

the big decision, the vibe check of the whole struct:

• 1 = we do openssl init 🔥
• 0 = leave it to the application 👑

so either the library handles the openssl init for you, or you're taking that task on yourself. no in-between, no "kinda sorta", just pick a lane bestie 💀
