GQOPSG(3NCARG)

✨ GQOPSG ✨ (aka the NCAR Graphics girlies' guide to Inquire name of open segment)

okay bestie, pull up a chair, we're in the 3NCARG section of the manual and this one is short and sweet but like, actually so useful 💖

GQOPSG returns the name of the currently open segment. that's it. that's the whole vibe. 🎀

🌸 SYNOPSIS 🌸

CALL GQOPSG(ERRIND,SGNA)

🦋 C-BINDING SYNOPSIS 🦋

#include <ncarg/gks.h>

void ginq_name_open_seg(Gint *err_ind, Gint *name_open_seg);

---

💅 DESCRIPTION 💅

• ERRIND (Integer, Output) — so here's the tea: if the GKS state is SGOP (segment open), then ERRIND comes back as "0" ✨. otherwise? ERRIND is returned as "4". no in-between, it's giving binary, it's giving yes-or-no, periodt.
• SGNA (Integer, Output) — if the GKS state is SGOP (segment open), then SGNA is returned as the number of the currently open segment, iconic, we love a lil name reveal 👑. otherwise SGNA is undefined. like, not zero, not garbage-with-a-vibe, just undefined — do not look at it, do not touch it, do not build your whole plot on it. 🫶

🚨 real talk: if you're not in SGOP, SGNA is undefined. check ERRIND first, always. no cap.

🎀 ACCESS 🎀
