LINED(3NCARG)

💖 LINED 💖 (that's the NCAR Graphics manual, bestie)

okay so real quick — this page lives in the NCAR Graphics manual, section 3NCARG. it's literally just one little function and it's lowkey iconic. 🎀

---

✨ NAME ✨

LINED — draws a line segment between two points whose user coordinates are given. that's it. that's the whole job. and it ATE. 💅

---

🌸 SYNOPSIS 🌸

CALL LINED (XA,XB,YA,YB)

---

🦋 C-BINDING SYNOPSIS 🦋

#include <ncarg/ncargC.h>

void c_lined (float xa, float xb, float ya, float yb)

---

💜 DESCRIPTION 💜

okay so here's the tea on the arguments. read them carefully bestie, they're in a weird order and you WILL mix up XA and XB if you're not paying attention:

• XA — an input expression of type REAL. this is the X user coordinate of the starting point of your line segment. 🌸
• YA — an input expression of type REAL. this is the Y user coordinate of the starting point of your line segment. 💖
• XB — an input expression of type REAL. this is the X user coordinate of the ending point of your line segment. ✨
• YB — an input expression of type REAL. this is the Y user coordinate of the ending point of your line segment. 🦋

so it goes start-X, end-X, start-Y, end-Y. not start-X, start-Y, end-X, end-Y. i know. i KNOW. just double check it every single time, no cap. 🙈

🎀 C-BINDING DESCRIPTION 🎀

the C-binding argument descriptions are the same as the FORTRAN argument descriptions. literally identical. same four floats, same order, same energy. so if you read the FORTRAN bit above you're already done here, you're so ahead of the game bestie. 👑

🌈 EXAMPLES 🌈

want to actually see this thing doing its little thing? run the ncargex command to check out these relevant examples:

tdashc, tdashl, tdashp, tdashs, fcoord1, fcoord2, fdldashc, fdldashd, fgklnclr, fgklnwth dashdb, dashdc, frstd, lined, reset, vectd, ncarg_cbind

go forth and run them, it's giving study session 📚✨

---

🔥 ACCESS 🔥

to use LINED or c_lined, you gotta load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c — preferably in that order. order matters, don't be chaotic about it. 🫶

okay that's the whole page bestie, you're officially a LINED expert now, go draw some gorgeous little line segments and slay 💖✨🎀🦋🌸💅

this was page LINED(3NCARG) from the UNIX manual, dated March 1993 — yes she's vintage, yes she still serves. bye bestie, ily, drink some water 🍓🧚💜
