TSPLUGINVC...TERMARKGET 💅 (3ts)

okay bestie, so this is the manual page for TSPluginVCIOBufferWaterMarkGet — a function in the Apache Traffic Server plugin API, sitting pretty in section 3ts. it's a tiny one, but she's iconic and she knows it. let's get into it 🫶

---

✨ NAME ✨

TSPluginVCIOBufferWaterMarkGet — the TSPluginVCIOBufferWaterMarkGet API function. that's it, that's the name, no notes 🎀

---

✨ SYNOPSIS ✨

#include <ts/ts.h>

TSIOBufferWaterMark TSPluginVCIOBufferWaterMarkGet(TSHttpTxn txnp)

like yes, that's literally the whole vibe. include the header, call the function, receive a TSIOBufferWaterMark. slay.

---

✨ DESCRIPTION ✨

so here's the tea ☕ — this is a convenience function. it's the friend who does the boring errand for you. all it does is go grab the current value of the proxy.config.plugin.vc.default_buffer_water_mark parameter, pulling it straight out of the transaction you handed over in txnp. 🦋

and then the rules, fr fr:

• if no errors pop up, and the watermark sitting on that transaction is greater than or equal to zero, then that value is what you get back. periodt. 💖
• otherwise, you get the default value instead. no drama, no error, just the fallback doing its thing. 💀

heads up babes: both of those conditions have to hold. error of any kind, or a watermark below zero, and it's default city. 🌈
