GOPKS(3NCARG)

GOPKS(3NCARG) 💖

okay bestie, welcome to the NCAR GRAPHICS corner of the manual, this is gopks, and she is literally the opening act — the girl who opens the GKS package for you. no cap.

✨ NAME ✨

gopks — opens the GKS package 🎀

✨ SYNOPSIS ✨

CALL GOPKS (ERRFIL, BUFA)

✨ C-BINDING SYNOPSIS ✨

like, for the C girlies 🫶

#include <ncarg/gks.h>

void gopen_gks(const char *err_file, size_t mem_unit);

✨ DESCRIPTION ✨

• ERRFIL — (Input, Integer) — the Fortran unit number where your error messages are gonna get written. typically you want this to be unit 6. that's the vibe. 💅
• BUFA — (Input, Integer) — the dimension of an internal buffer. and here's the tea ☕: currently in NCAR GKS-0A, BUFA is ignored. like she's there, she's invited, but she's not doing anything. iconic of her honestly.

✨ USAGE ✨

so to get output to any workstation, you gotta call these three in this exact order, no skipping, no shuffling:

1. GOPKS
2. GOPWK
3. GACWK

order matters bestie, do NOT freestyle this 💀

BUT — and this is the plot twist 🌸 — if your job is producing only CGM output, you can replace all three of those calls (GOPKS, GOPWK, GACWK) with a single call to the SPPS function OPNGKS. one call instead of three. lowkey efficient. ate. ✨

✨ ACCESS ✨

to use GKS routines, you gotta load the NCAR GKS-0A library ncarg_gks. that's the key to the whole kingdom, fr fr. 🔑
