SASL_USER_EXISTS(3)

💖 sasl_user_exists — bestie edition ✨

okay so real talk, this is sasl_user_exists(3), one of the little cuties from the Cyrus SASL manual (section 3, we're in library-call territory, very demure, very coder girl 💅).

---

🌸 NAME 🌸

sasl_user_exists — Cyrus SASL documentation 🫶

---

✨ SYNOPSIS ✨

no cap, here's the vibe, copy it exactly:

#include <sasl/sasl.h>

int sasl_user_exists( sasl_conn_t *conn,
                      const char *service,
                      const char *user_realm,
                      const char *user)

---

🦋 DESCRIPTION 🦋

same signature, one more time because she's iconic:

int sasl_user_exists( sasl_conn_t *conn,

const char *service,

const char *user_realm,

const char *user)

so like… what does she do? sasl_user_exists will check if a user exists on the server. that's it, that's the whole job, and she ate. 🔥

🎀 Parameters 🎀

the way that every single one of these matters, let's go:

• conn – the SASL context for this connection (your main character, lowkey)
• service – Service name, or NULL (and if you pass NULL, it uses the service name of the connection context 🌈)
• user_realm – Realm to check in, or NULL (and NULL here means the default realm, periodt)
• user – User name to check for existence. literally just the name, bestie. 👑

---

💜 RETURN VALUE 💜

SASL functions should return SASL return codes — that's the whole system, no exceptions. peek at sasl.h for a complete list if you wanna see all of them, because there are many. and for the record: SASL_OK indicates success. so if you see SASL_OK, you're slaying. if you don't… 😭 vibe check failed, go read the error codes.
