font_data_export(9)

📦 version 7.3.1, in nixpkgs unstable

okay bestie, welcome to font_data_export(9) from the Kernel API Manual — we're storing font data for user space and looking iconic while we do it ✨💅

🎀 NAME 🎀

font_data_export - Stores font data for user space. That's the whole assignment, no cap: font data for user space, stored. 🦋

✨ SYNOPSIS ✨

the signature, verbatim so nobody comes for me:

       int font_data_export (font_data_t *fd , struct console_font *font ,
       unsigned int vpitch );

🫶 ARGUMENTS 🫶

  • fd — Font data. Your font-data bestie, the thing being passed in 💖
  • font — A font for user space. It's the font the data gets stored into, periodt ✨
  • vpitch — The size of a single glyph in font in bytes. Literally that number, in bytes 🎀

💖 DESCRIPTION 💖

Store the font data given in fd to the font in font. Values and pointers in font are pre-initialized. This helper mostly checks some corner cases and translates glyph sizes according to the value given vpitch.

so yes: it's not doing a whole dramatic makeover, it's checking the lil corner cases and translating glyph sizes based on vpitch 🧚

🌈 RETURN 🌈

0 on success, or a negative errno code otherwise. That's the return story, short and sweet 😭💜
