xxxfb_pan_display(9)

✨ xxxfb_pan_display 💅

okay so real talk, bestie — this is a page from the Kernel API Manual about xxxfb_pan_display, and the very first thing you need to know is right there in the name section, so buckle up 🫶

🌸 NAME 🌸

xxxfb_pan_display — NOT a required function. (yes, the manpage is yelling that at you in all caps, it's giving main character energy 😭) it pans the display. that's the whole vibe.

---

⭐ SYNOPSIS ⭐

int xxxfb_pan_display (struct fb_var_screeninfo *var , struct fb_info
*info );

literally that's it, that's the signature, copy it exactly bestie, no cap 🔥

---

🎀 ARGUMENTS 🎀

• var — the frame buffer variable screen structure. it's the one holding all the variable-ish screen info ✨
• info — the frame buffer structure that represents a single frame buffer. one struct, one framebuffer, that's her 👑

---

🦋 DESCRIPTION 🦋

okay so what does it actually do? it pans (or wraps — depends on the vmode field, iykyk) the display using the xoffset and yoffset fields of the var structure. very demure, very mindful 🌸

and if those values don't fit? it returns -EINVAL. no discussion, no negotiation, just -EINVAL 💀

as for the return value: negative errno on error, or zero on success. that's the whole story, periodt 💅
