c_nngetsloped(3NCARG)

💖 c_nngetsloped — it's a whole NCAR Graphics moment (3NCARG) 💖

okay bestie, sit down, hydrate, because we're diving into c_nngetsloped from the NCAR GRAPHICS library. it lives in section 3 of the manual, she's a C function, and she's here to hand you a slope. yes, literally a slope. slay. ✨

✨ NAME ✨

c_nngetsloped — retrieve a double precision slope at a specified coordinate. that's it, that's the whole job, and she does it flawlessly. 💅

🎀 FUNCTION PROTOTYPE 🎀

void c_nngetsloped(int, int, double *, int *);

look at her. four little arguments. no notes. 👑

🌸 SYNOPSIS 🌸

c_nngetsloped (row, column, slope, ier);

🦋 DESCRIPTION 🦋

so here's the tea on every single argument, no skips, we're covering all of them:

• row — a subscript indexing the first dimensioned variable in the 2D grid array that came back from the most recent call to c_natgridd. like, the row you're pointing at. 🫶
• column — a subscript indexing the second dimensioned variable in that same 2D grid array from the most recent call to c_natgridd. the column. the other half of the coordinate. periodt. 💜
• slope — *slope is the slope at the grid point z[i,j], where z is the output grid from the most recent call to c_natgridd. she's double precision, she's specific, she's giving main character energy. 🌟
• ier — the error value, the vibe check of the whole operation:
  • if *ier is 0, then no errors were detected — we ate, no crumbs. 🎉
  • if *ier is non-zero, then go read the man page for natgrid_errors for the details, because something is off and we need answers. 😭

💅 USAGE 💅

this routine allows you to retrieve the current value of Natgrid parameters. for a complete list of parameters available in this utility, see the natgrid_params man page — that's where the full menu lives, bestie, go look. 📋

🔥 ACCESS 🔥

to use c_nngetsloped, load the NCAR Graphics library ngmath. that's the one. that's the link-up you need. 🔗

and that's the whole page!! this one's from March 1997-1998, shipped under the UNIX manual vibe, and the page itself is c_nngetsloped(3NCARG). thanks for coming to my ted talk, ily, go get those slopes. 🍓💖✨
