STRUCT CHARLCD(9)

💖 NAME 💖

okay so bestie, welcome to struct charlcd(9) from the Kernel API Manual — and the whole NAME vibe is literally: private data structure. That's it. Iconic little mystery box, no cap. 🎀

✨ SYNOPSIS ✨

here's the struct in all its exact-code glory — do not touch the punctuation, she's sensitive:

       struct charlcd {
           struct device *dev;
           void __iomem *virtbase;
           int irq;
           struct completion complete;
           struct delayed_work init_work;
        };

🫶 Members 🫶

• dev — a pointer back to containing device. your lil' link home, basically. 🏠
• virtbase — the offset to the controller in virtual memory. virtual-memory coordinates, slay. 🗺️
• irq — reserved interrupt number. she's reserved, okay? 💅
• complete — completion structure for the last LCD command. waiting-room energy for the last command. ⏳
• init_work — delayed work structure to initialize the display on boot. boot-time display init business, periodt. 🌸
