GINQ_CHAR_UP_VEC(3NCARG)

💖 GINQ_CHAR_UP_VEC 💖

okay so bestie, welcome to ginq_char_up_vec, a lil function from the NCAR GRAPHICS manual page family (you'll see it filed under 3NCARG in the UNIX section, dated March 1993 — vintage but make it fashion ✨).

✨ NAME ✨

ginq_char_up_vec — it retrieves the current value of the character up vector 🎀

like, it inquires. it asks the question. it does not set anything, it's giving main character observation energy 💅

🌸 SYNOPSIS 🌸

#include <ncarg/gks.h>

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

🦋 DESCRIPTION 🦋

okay so here's the tea on the parameters, one by one, no skips 🔥

• err_ind — (Output) — if the inquired values can't be returned correctly, a non-zero error indicator gets dropped into err_ind. otherwise? it's a zero. bestie if you wanna know what the error indicators mean, you gotta go consult the "User's Guide for NCAR GKS-0A Graphics" — that's the lore, i don't make the rules 📖
• char_up_vec.delta_x — (Gfloat, Output) — gives the X world coordinate of a the up vector. (yes, "a the". iconic typo energy, we keep it exactly as written 💀)
• char_up_vec.delta_y — (Gfloat, Output) — gives the Y world coordinate of a the up vector.

🧚 USAGE 🧚

so the up vector is literally that vector formed by the two coordinate points (0.,0.) and (char_up_vec.delta_x,char_up_vec.delta_y). that's the whole vibe. 📐

and if you want more details on the meaning of the character up vector, go see gset_char_up_vec — she's the one who sets it, this function just asks about it 🫶

👑 ACCESS 👑

to use the GKS C-binding routines, you gotta load the ncarg_gks and ncarg_c libraries. load them. both. no cap 🔥
