QB_IPCS_E...UFFER_SIZE(3)

💖 QB_IPCS_E...UFFER_SIZE 💖

okay bestie, this one lives in the libqb Programmer's Manual (section 3, the function-call section, iykyk) and it's literally one of the smallest little functions ever, but it has main character energy for your buffer sizes. Let's get into it. 🎀

---

✨ NAME ✨

qb_ipcs_enforce_buffer_size — enforce the max buffer size clients must use, from the server side. server says jump, clients say how high. periodt. 👑

---

🌸 SYNOPSIS 🌸

#include <qb/qbipcs.h>

void qb_ipcs_enforce_buffer_size(
    qb_ipcs_service_t   *s,             /* ipc server instance */
    uint32_t             max_buf_size   /* represented in bytes */
);

---

🦋 PARAMS 🦋

• s — the ipc server instance. your server, your rules 💅
• max_buf_size — represented in bytes. yes, bytes, not vibes. actual bytes.

---

📝 DESCRIPTION 📝

this is where the drama is. there's no big paragraph here, just the important note below. go read it, it's giving "one sentence that changes everything". 😭

---

💡 NOTE 💡

Setting this will force client connections to use at least max_buf_size bytes as their buffer size.

and lowkey the flip side matters too: if this value is not set on the server, the clients enforce their own buffer sizes. so somebody's always enforcing something around here, fr fr. 🫶
