GKS(3NCARG)

💖 GKS — the whole vibe, explained 💖

okay so bestie, welcome to the NCAR GRAPHICS corner of the man pages, page GKS(3NCARG). sit down, grab a strawberry 🍓, because this one is a whole collection.

GKS — the Graphical Kernel System — is a set of low-level graphics functions, and it's not just Some Guy's opinion: it's standardized by the American National Standards Institute (ANSI) and the International Standards Institute (ISO). iconic behavior, honestly. 👑

The collection of man pages in 3NCARG reflects those GKS functions documented in the NCAR UserDoc "User's Guide for NCAR GKS-0A Graphics". Heads up though: this collection does not contain all of the functions in GKS-0A — it's just the most frequently used ones. Lowkey a greatest-hits album. 🎀

But here's the thing: NCAR GKS-0A itself does contain all of the functions required to be implemented by the GKS Standard. So the library is complete, the man page collection is curated. slay.

🎀 ACCESS 🎀

wanna actually use any of the functions in NCAR GKS? then you gotta load the NCAR GKS library, bestie:

ncarg_gks

that's the whole thing. load ncarg_gks, that's it, that's the access step. 💖

🦋 MESSAGES 🦋

when things go sideways and something yells at you: see the UserDoc "User's Guide for NCAR GKS-0A Graphics" for a complete list of error numbers and messages. that's where the receipts live. 🧚

okay that's the whole page, you ate it, periodt. 👑

this was GKS(3NCARG) from the UNIX manual, dated March 1993 — shoutout to that date for being older than basically everyone reading this. mwah, bye bestie 💜✨
