GQCHUP(3NCARG)

✨ GQCHUP ✨

okay so bestie, welcome to the NCAR GRAPHICS section of the manual (that's the 3NCARG vibe iykyk) — and today's main character is GQCHUP, which stands for Inquire character up vector. It's literally just: go ask the system "hey, what's the current value of the character up vector?" and it tells you. That's the whole gig. 💅

🌸 NAME 🌸

GQCHUP (Inquire character up vector) — retrieves the current value of the character up vector. no cap, that's it, that's the job 🫶

💖 SYNOPSIS 💖

CALL GQCHUP (ERRIND, CHUX, CHUY)

🎀 C-BINDING SYNOPSIS 🎀

#include <ncarg/gks.h>

void ginq_char_up_vec(Gint *err_ind, Gvec *char_up_vec);

🦋 DESCRIPTION 🦋

okay so here's what you're handing it, and what it hands back 👇

• ERRIND — (Integer, Output) — if the inquired values can't be returned correctly, you get a non-zero error indicator dropped into ERRIND. otherwise? you get a zero. clean. ✨ Consult "User's Guide for NCAR GKS-0A Graphics" for a description of the meaning of the error indicators — that's where the lore lives, bestie.
• CHUX — (Real, Output) — gives you the X world coordinate of a the up vector.
• CHUY — (Real, Output) — gives you the Y world coordinate of a the up vector.

🌈 USAGE 🌈

the up vector is that vector formed by the two coordinate points (0.,0.) and (CHUX,CHUY). that's the whole geometry of it, periodt. 📐

if you want the full tea on what the character up vector actually means, go read GSCHUP — it's the one with more details on the meaning of the character up vector. this page is just the "what's the value rn" girlie. 💁‍♀️

👑 ACCESS 👑

to use GKS routines, load the NCAR GKS-0A library ncarg_gks. load it. don't skip it. 🔥
