PLSMEM(3plplot)

💅 PLSMEM 💅

Okay so bestie, real talk — this is the plsmem page from the PLplot API, and it's literally the glow-up moment where you hand PLplot a chunk of your own memory and say "here, draw on this." Iconic behavior. Let's get into it.

---

✨ NAME ✨

plsmem — set the memory area to be plotted (RGB). That's it, that's the vibe. 🎀

---

🦋 SYNOPSIS 🦋

plsmem(maxx, maxy, plotmem)

Short. Sweet. Slay. 💅

---

🌸 DESCRIPTION 🌸

So here's the tea, bestie: plsmem sets the memory area to be plotted (with the mem or memcairo driver) as the dev member of the stream structure. That's the whole assignment, and it ate. 🔥

It also sets the number of pixels in the memory you pass in plotmem, which is a block of memory maxy by maxx by 3 bytes long — like, say: 480 x 640 x 3 (Y, X, RGB). Note the order, bestie: Y first, then X, then RGB. Don't come for me, that's just how it is. 👑

⚠️ Heads up, no cap: this memory will have to be freed by the user! PLplot is not your cleanup crew, she's just the artist. You allocated it, you free it. Periodt. 💀

The redacted form is: plsmem(maxx, maxy, plotmem) — literally the same thing, just chiller.

And lowkey? This function is not used in any examples. She's a mysterious main character who doesn't do cameos. 🙈

🧚 ARGUMENTS 🧚

• maxx (PLINT(3plplot), input) — size of the memory area in the X coordinate. X marks the spot, bestie. 🌈
• maxy (PLINT(3plplot), input) — size of the memory area in the Y coordinate. Y tho. 💜
• plotmem (PLPointer(3plplot), input) — pointer to the beginning of a user-supplied writeable memory area. Like, you bring the canvas, okay? 🎨
