rtcRetainBuffer(3)

💖 rtcRetainBuffer(3) — Embree Ray Tracing Kernels 4 💖

okay bestie, gather round, we're doing reference counting today and honestly? it's giving "tiny function, huge responsibility." this is the rtcRetainBuffer page from the Embree Ray Tracing Kernels 4 manual, and yes it's short, but every word eats. 🫶

✨ NAME ✨

rtcRetainBuffer — increments the buffer reference count 🔥

🌸 SYNOPSIS 🌸

#include <embree4/rtcore.h>

void rtcRetainBuffer(RTCBuffer buffer);

like, that's it. one include, one call, one void. no cap. 💅

🦋 DESCRIPTION 🦋

so. buffer objects are reference counted. that's the whole vibe of this function, okay?

rtcRetainBuffer bumps up the reference count of the buffer object you hand it — that's the buffer argument, in case you were wondering which buffer. (it's that one. the one you passed. 💀)

and here's the part that's actually iconic: this function, together with rtcReleaseBuffer, lets you use the internal reference counting inside a C++ wrapper class to handle the ownership of the object. so you're not out here manually tracking who owns what like it's 1998 — the counting does it for you. main character energy fr fr ✨

😭 EXIT STATUS 😭

if something goes wrong — on failure — an error code gets set, and you can go query it with rtcGetDeviceError. so like, if it's acting sus, that's where you check. 🙈

👑 SEE ALSO 👑

• rtcNewBuffer — the one that makes the buffer in the first place 🌱
• rtcReleaseBuffer — the one that gives the count back, the other half of this whole dynamic 🎀

real talk: retain and release are a pair. if you retain and never release, that's a leak, and the leak is not cute. balance your counts, bestie. ⭐

that's the whole page, we ate, no crumbs left. this was rtcRetainBuffer(3) from the Embree Ray Tracing Kernels 4 manual. go forth and count your references responsibly 💖✨🎀
