STRUCT NFP_CCM_MBOX_CMSG_CB(9)

💅 NAME

struct nfp_ccm_mbox_cmsg_cb — literally just the CCM mailbox specific info 🎀

okay so this is a Kernel API Manual entry (yes that's the manual name, hi 👋) and it's about one little struct that holds all the deets about a CCM mailbox message, no cap 💖

✨ SYNOPSIS

struct nfp_ccm_mbox_cmsg_cb {
    enum nfp_net_mbox_cmsg_state state;
    int err;
    unsigned int max_len;
    unsigned int exp_reply;
    bool posted;
};

that's the whole vibe 😌 five fields, all iconic, all doing their job 🫶

🎀 Members

• state — the processing state (/stage) of the message 👑 she's in her processing era fr
• err — the error that got encountered during processing, if any 😭 key phrase: if any — no error means this is chillin' empty
• max_len — literally max(request_len, reply_len) — she takes the bigger of the two, periodt 💅
• exp_reply — the expected reply length 📏 and bestie listen: 0 means don't validate — that's the "no thoughts head empty, trust the process" setting 🙈
• posted — the message was posted and nobody waits for the reply 💀 not a single soul in the queue for that answer, she's on her own main character energy
