linedisp_attach(9)

🎀 NAME 🎀

linedisp_attach - attach a character line display

Okay bestie, this page is from the Kernel API Manual, and the star is linedisp_attach(9). It attaches a character line display. Literally that's the whole vibe. 💅

✨ SYNOPSIS ✨

int linedisp_attach (struct linedisp *linedisp , struct device *dev ,
       unsigned int num_chars , const struct linedisp_ops *ops );

🌸 ARGUMENTS 🌸

• linedisp — pointer to character line display structure. The display object itself, front and center.
• dev — pointer of the device to attach to. This is the device getting the attach treatment.
• num_chars — the number of characters that can be displayed. Literally the character budget, no cap.
• ops — character line display operations. The ops crew for the display.

💖 DESCRIPTION 💖

Directly attach the line-display sysfs attributes to the passed device. It's giving direct attachment, very much on purpose. 🦋

The caller is responsible for calling linedisp_detach to release resources after use. Like, do not forget — that resource release is on you, bestie. Periodt.

This is a direct attach to the device you pass in, and linedisp_detach is the call you need after use to release resources. No skipping the cleanup arc. 🙈

🔥 RETURN 🔥

zero on success, else a negative error code. So success is zero, and negative means error. Simple, iconic. 😭
