drm_coredump...nter_is_full(9)

💅 drm_coredump_printer_is_full — a Kernel API Manual moment 🎀

okay so bestie, we're in the Kernel API Manual today and the star of the show is drm_coredump_printer_is_full(9). yes the header truncates it to drm_coredump...nter_is_full(9) (rude of it honestly) but we know her full name and we respect her 💖

✨ NAME ✨

drm_coredump_printer_is_full — DRM coredump printer output is full. that's it, that's the vibe check 🦋

---

✨ SYNOPSIS ✨

bool drm_coredump_printer_is_full (struct drm_printer *p );

like, she takes a printer and returns a bool. iconic signature, no notes 👑

---

✨ ARGUMENTS ✨

• p — the DRM coredump printer. that's the whole argument list, she's low-maintenance 🎀

---

✨ DESCRIPTION ✨

so the DRM printer output is full — and this function is the one that tells you that. it's genuinely useful for short-circuiting coredump printing once the printer is full, so you're not out here printing into the void like 😭🔥

ngl this is the "bestie the buffer is FULL, stop" of kernel functions and I respect the honesty.

---

✨ RETURN ✨

• True — if the DRM coredump printer output buffer is full 💀
• False — otherwise 🌸

literally a binary. main character energy.
