get_default_font(9)

📦 version 7.3.1, in nixpkgs unstable

💅 get_default_font(9) — like, the Kernel API Manual era 🎀

okay bestie, sit down, hydrate, and let me tell you about get_default_font — it's a kernel API manual page (yes, manual nine, the kernel one, iykyk) and it is literally the vibe-checker for picking a default font for a screen. no cap, it's giving "matchmaker but for pixels" 💖

✨ NAME ✨

get_default_font — get default font 🫶

✨ SYNOPSIS ✨

const struct font_desc * get_default_font (int xres , int yres ,
       unsigned long *font_w , unsigned long *font_h );

that's the whole signature, copy it exactly, don't freestyle it 😭

✨ ARGUMENTS ✨

  • xres — screen size of X. yep. that X. 📐
  • yres — screen size of Y. the other one. 📏
  • font_w — bit array of supported widths, and the range is 1 - FB_MAX_BLIT_WIDTH ⭐
  • font_h — bit array of supported heights, range 1 - FB_MAX_BLIT_HEIGHT 🦋
not me pointing out that these are bit arrays — they are, fr fr, don't come for me 💅

✨ DESCRIPTION ✨

so basically: get the default font for a specified screen size. that's the whole plot. dimensions are in pixels 📐✨

and here's the cute part — if font_w or font_h is NULL, that means, like, all values are supported. no constraints, no filter, we're going feral, everything is valid 🌈

it returns NULL if no font is found 😭 (sad, tragic, devastating), or a pointer to the chosen font 👑 (slay).

⚠️ quick recap because it matters: NULL return = nothing found. pointer return = the chosen font. do not mix those up bestie 💀

✨ SEE ALSO ✨

Kernel file ./lib/fonts/fonts.c — go read it, it's the main character 📖

and that's the page!! no notes, ate and left no crumbs 💅✨ this lil gem lives over in ./lib/fonts and it's dated October 2026 — yes, we're posting from the future, obsessed 🦋💜
