STRUCT SOCKADDR_CAN(9)

okay so bestie, this is the struct sockaddr_can(9) page from the Kernel API Manual, section 9 — and it’s literally the sockaddr structure for CAN sockets. iconic kernel-address energy, no cap 💅

✨ NAME ✨

struct sockaddr_can — the sockaddr structure for CAN sockets. that’s the whole vibe, fr fr 🫶

🌸 SYNOPSIS 🌸

here’s the struct exactly as it is, no edits, no “i fixed it” behavior:

       struct sockaddr_can {
           __kernel_sa_family_t can_family;
           int can_ifindex;
           union {
             struct {
               canid_t rx_id, tx_id;
             } tp;
             struct {
               __u64 name;
               __u32 pgn;
               __u8 addr;
             } j1939;
           } can_addr;
        };

🎀 Members 🎀

• can_family — the address family number, and it’s AF_CAN. that’s the family field, bestie 🌸
• can_ifindex — the CAN network interface index. it’s giving “which interface are we talking about” 👑
• can_addr — protocol specific address information. this is the address-info part, protocol-specific and all 💫

🔥 SEE ALSO 🔥
