✨ TSHTTPTXN...CKETTOSSET(3ts) ✨

okay bestie, we're in the Apache Traffic Server manual, section 3ts, and today's main character is a lil function called TSHttpTxnClientPacketTosSet. she's short, she's sweet, she does exactly one thing. let's get into it 💅

🌸 NAME 🌸

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

🦋 SYNOPSIS 🦋

#include <ts/ts.h>

TSReturnCode TSHttpTxnClientPacketTosSet(TSHttpTxn txnp, int tos)

so you pull in <ts/ts.h> and then you're handed back a TSReturnCode, and you feed her a TSHttpTxn txnp plus an int tos. two args, one return value, no drama ✨

💖 DESCRIPTION 💖

she changes the packet tos for the client side connection. that's the vibe. that's the whole job. 🫶

IMPORTANT: changes take effect immediately. like, immediately immediately. no queue, no "next cycle", no waiting room. she does not do delayed gratification, bestie. 👑
NOTE: TOS is deprecated and has been replaced by DSCP. it's still what you use to set DSCP, but heads up — the first 2 bits of this value will be ignored, because those bits now belong to the ECN field. so if you're sitting there wondering why your top two bits are giving nothing... that's why. not your fault, not a bug, just the assignment of bits changing hands 💀

🔥 SEE ALSO 🔥

lowkey empty in here 😭 no cross-references listed, so this section is just a cute little room with no furniture. if you were hoping for a "go read this next" moment — nope, that's the whole section, fr fr.

and that's the page, bestie — you came, you read, you understood a socket-level packet field, main character energy fr 🌈
