IDGETR(3NCARG)

✨ IDGETR ✨

okay bestie, welcome to the NCAR Graphics manual, and specifically to IDGETR — the lil routine that goes and fetches you the real value of a Bivar parameter 💖

---

🎀 NAME 🎀

IDGETR — retrieves the real value of a Bivar parameter. that's it, that's the whole job, and she does it flawlessly 💅

---

🌸 SYNOPSIS 🌸

CALL IDGETR (PNAM,RVAL)

---

🦋 C-BINDING SYNOPSIS 🦋

#include <ncarg/ncargC.h>

void c_idgetr (char *pnam, float *rval)

---

💜 DESCRIPTION 💜

okay so here's the tea on the arguments, no cap:

• PNAM — (an input constant or variable of type CHARACTER) this is the name of the parameter you wanna retrieve, bestie. the character string can literally be any length you want, BUT 👀 only the first two characters of it will be examined. so like, don't get cute with the long names, she's only reading the first two. iykyk.
• RVAL — (an output variable of type REAL) a real variable that receives the parameter value you asked for. here's the vibe check: if the internal parameter is of type REAL and has the value "r", then RVAL gets the value "r". and if the internal parameter is of type INTEGER and has the value "i", then RVAL gets the value "REAL(i)". conversion slay ✨

🌈 C-BINDING DESCRIPTION 🌈

the C-binding argument descriptions are the same as the FORTRAN argument descriptions. periodt. no notes 💅

---

👑 USAGE 👑

this routine lets you retrieve the current value of Bivar parameters. it's giving very much "hey what's the setting rn" energy 🫶

for a complete list of parameters available in this utility, see the bivar_params man page. go look, she's thorough.

---

🍓 ACCESS 🍓

to use IDGETR or c_idgetr, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in that order. order matters bestie, don't be chaotic 🙈

---

💀 MESSAGES 💀

see the bivar man page for a description of all Bivar error messages and/or informational messages. if something's going sideways, that's where the receipts live.

okay that's the whole page, you ate that fr fr 💖

and that's a wrap on the IDGETR(3NCARG) page from the NCAR Graphics crew — she's been serving since November 1995 and she's still iconic ⭐ mwah, go retrieve some parameters, main character 🎀👑
