GLUTSTROKELENGTH(3)

✨ GLUTSTROKELENGTH ✨

okay bestie, so this is a page from the OpenGLUT manual, section 3 — glutStrokeLength(3), if we're being formal about it. it's giving "fonts, but make it math." 💖

---

🌸 NAME 🌸

glutStrokeLength — Returns model space width of a string in a given font.

like. it tells you how wide your little text is gonna be. model space. in a font. that's the whole vibe. 🎀

---

📚 LIBRARY 📚

OpenGLUT - fonts

that's the girlies we're hanging with today. fonts department. 💅

---

✨ SYNOPSIS ✨

#include <openglut.h>

float
glutStrokeLength(void *fontID, const unsigned char *string);

look at her. three lines. stunning. no notes. 😌

---

🦋 PARAMETERS 🦋

• fontID — a GLUT stroked font identifier. basically your "which font are we doing this in" ticket. 🎟️
• string — a C-style string, meaning it's NUL-terminated. it knows where it ends, no cap. 💀

---

🌈 DESCRIPTION 🌈

so the way this works, bestie: this function reports the sum of the widths of the characters in a string, using the font metrics of a given font.

that's it. that's the function. it adds up all the widths and hands you the total. main character energy. 👑

and like glutStrokeString(), glutStrokeLength() respects newlines in the input. so if your string has line breaks, it knows. it sees them. it's not gonna ignore them. 🫶

it returns 0 if:

• The fontID is out of range.
• The string is NULL.
• All characters in the string are zero-width.

so yeah, zero can mean "your font ID is sus," or "you passed me nothing," or "congrats, everything in here is invisible." three totally different disasters, same number. iconic, honestly. 😭

⚠️ CAVEATS ⚠️

real talk, go read glutStrokeWidth() for notes on the nature of this function's return value, and for comparisons to old GLUT and freeglut.

don't skip that part. it's important. it's the plot. 📖

and that's the whole page, bestie. this was a UNTITLED() situation from UNDATED — yeah, nobody signed it, nobody dated it, it just exists, like a mysterious little ghost note in the source tree. 🧚 stay slay, measure your strings responsibly. 💖✨
