SLGETR(3NCARG)

✨ SLGETR — get that real value, bestie ✨

okay so this is a page from the NCAR GRAPHICS manual, section 3NCARG, and it's all about one lil' Fortran routine called SLGETR 🎀

---

💖 NAME 💖

SLGETR — gets the current real value of an internal parameter of Scrolled_title of type INTEGER or REAL. 👑

and if you want the whole list of every Scrolled_title internal parameter, go look at the scrolled_title_params man page, fr fr. 📜

---

🌸 SYNOPSIS 🌸

CALL SLGETR (PNAM, RVAL)

that's it. that's the whole vibe. 💅

---

🦋 C-BINDING SYNOPSIS 🦋

#include <ncarg/ncargC.h>

void c_slgetr (char *pnam, float *rval)

yes bestie, there's a C version too, she's serving 🫶

---

✨ DESCRIPTION ✨

• PNAM — an input constant or variable of type CHARACTER, and she specifies the name of the parameter whose value you wanna retrieve. 👀 important lil detail: only the first three characters of the string are even looked at. so don't be out here typing a whole novel, she's reading three letters and moving on. 💀
• RVAL — an output variable of type REAL, and this is where the value of the internal parameter lands. here's the tea tho:
  • if the internal parameter is of type INTEGER and has the value "i", then RVAL = REAL(i) — she converts it for you, no cap 🔥
  • if the internal parameter is of type REAL and has the value "r", then RVAL = r — just straight through, as-is 🌈

---

💜 C-BINDING DESCRIPTION 💜

the C-binding argument descriptions are literally the same as the FORTRAN argument descriptions. same energy, different syntax. periodt. ✨

---

👑 USAGE 👑

this routine lets you retrieve the current value of Scrolled_title parameters. that's her whole job and she does it flawlessly, ngl. 🎀

and for a complete list of parameters available in this utility, see the scrolled_title_params man page — she's the master list, go pay her a visit. 📖

---

🔥 ACCESS 🔥

to use SLGETR or c_slgetr, you gotta load the NCAR Graphics libraries ncarg, ncarg_gks, ncarg_c, and ncarg_c — preferably in that order, bestie. don't fight the order, the order is iconic. 🧚

💌 MESSAGES 💌

see the scrolled_title man page for a description of all Scrolled_title error messages and/or informational messages. if something's yelling at you, that's where the answers live. 😭

and that's the whole page!! 🌈 source/version vibes: this one's from the UNIX manual, dated July 1995, tagged SLGETR(3NCARG). iconic behavior from 1995 honestly, she ate and left no crumbs 👑✨ bye bestie, go get those real values!! 🦋💖
