QB_IPCS_C...N_AUTH_SET(3)

💖 qb_ipcs_connection_auth_set 💖

okay so bestie, this one lives in the libqb Programmer's Manual, section 3 (yes, the library-functions girlies 💅). it's short, it's sweet, and it has exactly one rule you cannot fumble. let's get into it 🦋

---

✨ NAME ✨

qb_ipcs_connection_auth_set — the way this sets the permissions on and shared memory files so that both processes can read and write to them. both processes. reading AND writing. mutual. reciprocal. iconic. 🫶

---

🌸 SYNOPSIS 🌸

#include <qb/qbipcs.h>

void qb_ipcs_connection_auth_set(
    qb_ipcs_connection_t   *conn,  /* connection instance */
    uid_t                   uid,   /* the user id to set. */
    gid_t                   gid,   /* the group id to set. */
    mode_t                  mode   /* the mode to set.*/
);

like, it returns void. nothing comes back. no little success code, no little error code, nothing. she just does the thing 💜

---

🎀 PARAMS 🎀

• conn — connection instance. the connection in question, the one you're doing all this for 🌈
• uid — the user id to set.
• gid — the group id to set.
• mode — the mode to set. (yes, that kind of mode. permissions mode. not aesthetic mode, tho those are also important ✨)

---

💜 DESCRIPTION 💜

so um. the DESCRIPTION section is literally empty. nothing. a vibe. the void. 🕳️

the NOTE down there is the one carrying all the weight, so scroll your pretty eyes down like two whole lines, bestie 😭

---

⚠️ NOTE ⚠️

this must be called within the qb_ipcs_connection_accept_fn() callback.

not "you could." not "you might." must. if you call this anywhere else you're giving off main character energy in the bad way, no cap. call it inside the accept callback. periodt. 💅
