💖 FUNCTION::ENV_VAR 💖

okay so bestie, we're in the 3stap manual, which is the SystemTap Tapset Reference — yes, the whole context-functions girlie squad lives here. pull up a chair, this one's short and sweet and lowkey iconic. 🎀

✨ NAME ✨

function::env_var — fetch an environment variable from the current process 🫶

---

✨ SYNOPSIS ✨

env_var:string(name:string)

---

✨ ARGUMENTS ✨

• name — the name of the environment variable you wanna go grab, bestie. that's it, that's the whole argument. 💅

---

✨ DESCRIPTION ✨

so basically? it returns the contents of the environment value you specified, for the current process. that's the vibe. 🌸

and if that variable isn't set? you don't get an error, you don't get drama, you get an empty string. no cap. it's giving "sorry bestie, nothing here" but politely. 💀

fr fr, empty string ≠ error. don't be out here checking for failures that literally aren't happening.
