QB_IPCC_CONNECT(3)

QB_IPCC_CONNECT(3) — libqb Programmer's Manual ✨

🌸 NAME 🌸

qb_ipcc_connect — Create a connection to an IPC service. 💖

---

✨ SYNOPSIS ✨

#include <qb/qbipcc.h>

qb_ipcc_connection_t * qb_ipcc_connect(
    const char   *name,          /* name of the service. */
    size_t        max_msg_size   /* biggest msg size. */
);

---

🎀 PARAMS 🎀

• name — name of the service. literally the service's name, bestie.
• max_msg_size — biggest msg size. yes, the absolute biggest message size. 💅

---

💅 DESCRIPTION 💅

Okay so real talk: the DESCRIPTION section in the source is literally empty. Not one single line. It's giving minimalist queen, and we respect the silence. 🫶💀

---

🦋 RETURN VALUE 🦋

NULL (error: see errno) or a connection object.

So you either get NULL — which is the error vibe, check errno — or you get a connection object. periodt. 💖

---

👑 NOTE 👑

It is recommended to do a one time check on the max_msg_size value using qb_ipcc_verify_dgram_max_msg_size BEFORE calling the connect function when IPC_SOCKET is in use. Some distributions will allow large message buffers to be set on the socket, but not actually honor them because of kernel state values. The qb_ipcc_verify_dgram_max_msg_size function both sets the socket buffer size and verifies it by doing a send/recv. 🔥
