STRUCT ISSEI_HOST_CLIENT(9)

💖 NAME 💖

okay so bestie, this is the struct issei_host_client(9) page from the Kernel API Manual — yes, the manual name is folded right in here, we're being efficient ✨. In one line: this struct represents host client. That's the NAME vibe, no cap 💅.

✨ SYNOPSIS ✨

here's the whole struct, bestie — types, names, semicolons, all of it. Do not come for me about the indentation, I copied it exactly 🫶:

       struct issei_host_client {
           struct list_head list;
           struct issei_device *idev;
           u16 id;
           const struct file *fp;
           wait_queue_head_t write_wait;
           bool write_in_progress;
           enum issei_host_client_state state;
           struct issei_fw_client *fw_cl;
           wait_queue_head_t read_wait;
           u8 *read_data;
           size_t read_data_size;
        };

okay, member-by-member tour, no skipping, we are NOT leaving anyone out 👑:

• list — the link in host clients list 🔗
• idev — the issei parent device 🧸
• id — the host client id 🪪
• fp — the file associated with client 📁
• write_wait — the waitqueue for pending write data — it's giving "hold please" 🎀
• write_in_progress — the indicator for write in process 🚩
• state — the host client state 💅
• fw_cl — pointer to firmware client, if connected — only when connected, iykyk 🔌
• read_wait — the waitqueue for read object 🦋
• read_data — received data pointer 📥
• read_data_size — received data size 📏
