STAPVARS(3stap)

💖 NAME 💖

stapvars — systemtap variables, bestie. that's it, that's the whole name. slay ✨

🦋 DESCRIPTION 🦋

okay so here's the tea: the sections below are gonna walk you through all the public variables that the standard tapsets give you. (btw if you wanna know where those tapsets are even installed, the path is shown in the stappaths (7) manual page 👀)

every single variable gets described with a type, plus its behavior and restrictions, because we're thorough like that 💅

and the syntax? it's literally the exact same syntax you get printed out with the stap option -p2. no cap. fr fr.

examples, because a vibe check needs receipts:

example1:long

Variable "example1" contains an integer. simple. iconic.

example2:string [long]

Variable "example2" is an array of strings, indexed by integers. she's got range 💜

🌸 ARGV 🌸

• argc:long — this one holds the value of the $# value, which is the number of command line arguments passed to the systemtap script. and the way she gets initialized?? an implicit begin(-1) probe. periodt. 👑
• argv:string [long] — she holds each command line argument as a string, one by one. so like, argv[1] will equal @1 — but only if there was at least one command line argument to begin with. fair.

⚠️ lowkey important: arguments beyond #32 are not transcribed, and they produce a warning message inside that begin(-1) probe that initializes this array. so if you're out here throwing 33+ args at it, expect a lil warning bestie 😭

🎀 NULL 🎀

• NULL:long — simply defined as the number 0. that's it. no lore. no backstory. just zero. a minimalist queen 🫶

🍓 FILES 🍓
