NNG_STAT_STRING(3)

💖 NNG_STAT_STRING(3) — nng_stat_string 💖

okay bestie, so this one lives in the NNG Reference Manual and it's literally the glow-up your stats snapshot deserves. it's called nng_stat_string, and no cap, it's about to hand you a string. 🎀

---

✨ NAME ✨

nng_stat_string — bestie, it gets the statistic string value 🦋

✨ SYNOPSIS ✨

#include <nng/nng.h>

typedef struct nng_stat nng_stat;

const char *nng_stat_string(nng_stat *stat);

she's simple, she's clean, she's iconic 💅

✨ DESCRIPTION ✨

so nng_stat_string() returns a string value for the statistic stat, and stat must be of type NNG_STAT_STRING (go peek at nng_stat_type(3) if you need the receipts, iykyk).

now listen — if the statistic is not of type NNG_STAT_STRING, then NULL gets returned. that's it. that's the whole vibe check, and it failed. 🙈

note bestie 🫶 — the string you get back is valid until nng_stats_free() is called to free the memory for the snapshot. so like… use it, love it, don't hold onto it after the free, fr fr. it's giving borrowed, not given. 😭

✨ RETURN VALUES ✨

the string value associated with stat! 🎉 or NULL if the statistic is not a string type. that's literally the whole menu, bestie. no surprises, no drama. ✨

✨ ERRORS ✨

None. zero. zilch. not a single one. she doesn't miss. 💀👑
