DPGETR(3NCARG)

💖 DPGETR — it's giving "grab that real number, bestie" ✨

okay so this one is from NCAR GRAPHICS and it lives in section 3 of the manual, and honestly? she's a little legend. let's get into it 🫶

---

🌸 NAME 🌸

DPGETR — she retrieves the real value of an internal parameter of type REAL or INTEGER. that's it, that's the whole job, and she does it flawlessly 💅

---

✨ SYNOPSIS ✨

CALL DPGETR (PNAM,RVAL)

---

🎀 C-BINDING SYNOPSIS 🎀

#include <ncarg/ncargC.h>

void c_dpgetr (char *pnam, float *rval)

---

🦋 DESCRIPTION 🦋

• PNAM — an input expression of type CHARACTER, and she specifies the name of the parameter you're getting. the way this works: the name has to appear as the first three characters of the string. anything after that? purely for documentation vibes, no cap. like, instead of just writing ´LS1´, you can go all out and write ´LS1 - LABEL SPACING PARAMETER 1´ and it still works. iconic behaviour fr fr 📝
• RVAL — an output variable of type REAL, and she's the name of the variable where the value of the internal parameter specified by PNAM gets dropped off. here's the tea: if the internal parameter is a value "r" of type REAL, then the value returned is "r". but if the internal parameter is a value "i" of type INTEGER, then the value returned is "REAL(i)". so either way you're getting a REAL back, bestie, no surprises 💖

🌈 C-BINDING DESCRIPTION 🌈

the C-binding argument descriptions are the same as the FORTRAN argument descriptions. same energy, different syntax, we love a consistent queen ✨

---

👑 USAGE 👑

this routine lets you retrieve the current value of Dashpack parameters. and if you wanna see the complete list of parameters available in this utility, go check out the dashpack_params man page — she has the full menu 🍓

---

💜 ACCESS 💜

to use DPGETR or c_dpgetr, you gotta load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c — preferably in that order. don't be chaotic about the order, the order matters, trust 🙈

---

🔥 MESSAGES 🔥

for a description of all Dashpack error messages and/or informational messages, see the dashpack man page. she's got the whole gossip column 💀
