✨ NAME ✨

nng_log_set_level — set minimum level for logging messagse 🫶

ngl the original page has a lil typo in it ("messagse") and I am not fixing it, because keeping every detail is the whole vibe. iconic, honestly. 💅

🎀 SYNOPSIS 🎀

#include <nng/nng.h>

typedef enum nng_log_level {
        NNG_LOG_NONE   = 0, // used for filters only, NNG suppresses these
        NNG_LOG_ERR    = 3,
        NNG_LOG_WARN   = 4,
        NNG_LOG_NOTICE = 5,
        NNG_LOG_INFO   = 6,
        NNG_LOG_DEBUG  = 7
} nng_log_level;

void nng_log_set_level(nng_log_level level);

like… look at that enum. the numbers literally jump from 0 to 3 and it does NOT care. main character energy fr fr 😌

🌈 DESCRIPTION 🌈

so nng_log_set_level is the function you call when you want to set the minimum severity to level for processing log messages. that's the whole job. she's a filter and she knows it 👑

here's the tea: any messages with a less severe rating are not processed and are simply discarded. gone. not even a ghost. 💀

• want absolute silence? use NNG_LOG_NONE to suppress all log messages 🤫
• want literally everything? use NNG_LOG_DEBUG to receive all log messages 🗣️🔥

and remember bestie, NNG_LOG_NONE is = 0 and the comment says it's // used for filters only, NNG suppresses these — so it's a filter vibe, not a "print a message at level NONE" vibe. iykyk ✨
