GOPEN_GKS(3NCARG)

💖 NAME 💖

gopen_gks (aka Open GKS) — bestie, this is the one that opens the GKS package. First move of the whole graphics era, no cap. ✨

This lil cutie lives in the NCAR GRAPHICS section of the manual, page GOPEN_GKS(3NCARG) if you're keeping receipts. 📖💅

---

✨ SYNOPSIS ✨

#include <ncarg/gks.h>

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

---

🎀 DESCRIPTION 🎀

Okay so she takes two arguments, and here's the tea on both of them:

• err_file (Input) — the place where all the error messages get sent. Typically this should be "stdout". Like, that's the vibe. That's where the drama goes. 🗣️💬
• mem_unit (Input) — the dimension of an internal buffer. But ngl, currently in NCAR GKS-0A, mem_unit is ignored. She's just there. Decorative. A little main character who does nothing. 🙈 Ignore her back, it's only fair.

---

🌸 USAGE 🌸

Okay so if you want output to any workstation, you have to call these three in this exact order, bestie. The pipeline is real:

1. gopen_gks
2. gopen_ws
3. gactivate_ws

In that order. Periodt. Don't shuffle them like a playlist, they will not slay out of sequence. 💀

BUT — if your job is producing only CGM output, then you can skip the whole three-call ritual and just replace gopen_gks, gopen_ws, and gactivate_ws with a single call to the SPPS function c_opngks(). One call, all the same energy. Efficient queen behavior. 👑

💜 ACCESS 💜

Wanna use the GKS C-binding routines? Then you gotta load the ncarg_gks and ncarg_c libraries. Both. Load them. That's the toll to get in. 🎟️✨
