GQCHUP(3NCARG)
π GQCHUP β bestie, it's literally "Inquire character up vector" π
okay so this is a page from the NCAR GRAPHICS manual, section 3NCARG, and it's about a lil Fortran routine called GQCHUP. She's here to retrieve the current value of the character up vector. that's it. that's her whole job. and she eats every time π
β¨ SYNOPSIS β¨
like, the whole vibe in one line:
CALL GQCHUP (ERRIND, CHUX, CHUY)
π¦ C-BINDING SYNOPSIS π¦
for the C girlies (iykyk), same energy, different font:
#include <ncarg/gks.h>
void ginq_char_up_vec(Gint *err_ind, Gvec *char_up_vec);
πΈ DESCRIPTION πΈ
so here's the tea on each argument, no gatekeeping:
ERRINDβ (Integer, Output) β if the inquired values can't be handed back correctly, you get a non-zero error indicator dropped intoERRIND. otherwise? a big fat zero, slay. for the full lore on what the error indicators actually mean, go consult the "User's Guide for NCAR GKS-0A Graphics" π«ΆCHUXβ (Real, Output) β gives you the X world coordinate of the up vector.CHUYβ (Real, Output) β gives you the Y world coordinate of the up vector.
π USAGE π
ok so the up vector? she's the vector formed by those two coordinate points: (0.,0.) and (CHUX,CHUY). iconic geometry moment.
if you want the full backstory on what the character up vector even means, go peek at GSCHUP β she explains it all, periodt.
π₯ ACCESS π₯
to use the GKS routines, you gotta load the NCAR GKS-0A library: ncarg_gks. that's the entry fee, bestie, no cap.

not me making you read the legal bit but like. it's important. read it. π
ok that's the whole page, you're officially educated π this was the GQCHUP(3NCARG) page from the UNIX manual, dated March 1993 β yeah she's vintage, she's a classic, she's serving archive realness π¦β¨ mwah, go forth and inquire your character up vector, bestie π«Άπ
