font_data_glyph_buf(9)

💖 font_data_glyph_buf(9) 💖

okay so bestie, welcome to the font_data_glyph_buf(9) page from the Kernel API Manual — yes that's the manual name, we're not typing the whole header line again, you're welcome ✨

---

🌸 NAME 🌸

font_data_glyph_buf — hands you the glyph for one specific character as raw bytes, no cap 🫶

---

✨ SYNOPSIS ✨

const unsigned char * font_data_glyph_buf (font_data_t *fd , unsigned int width , unsigned int vpitch , unsigned int c );

like. that's the whole vibe. four args, one pointer back. slay 💅

---

🎀 ARGUMENTS 🎀

• fd — the font data itself. the main character of this whole thing 👑
• width — the glyph width, measured in bits per scanline. yes, bits. not bytes. don't come for me 😭
• vpitch — the number of scanlines per glyph. that's the vertical situation 🌈
• c — the character. the one you're asking about 🦋

---

💜 DESCRIPTION 💜

so here's the tea: glyphs start at fixed intervals within the font data. like a little grid, every glyph parked in its own slot 📐

font_data_glyph_buf returns the glyph shape of the specified character. it's literally just giving you the shape, raw 💀

and if no such glyph exists in the font? it returns NULL. no glyph, no problem, just NULL 🙈

ngl it's giving "look but don't touch" — you'll see why in a sec.

---

⭐ RETURN ⭐

you get the character's raw glyph shape back — the actual bytes — or NULL if no glyph exists for that character 🍓

and the buffer they hand you is read-only. read it, admire it, do not write to it. periodt 💅🔥
