FUNCTION::ASSERT(3stap)

💖 FUNCTION::ASSERT 💖 (that's a 3stap page, bestie, section 3 of the SystemTap tapsets)

✨ NAME ✨

function::assert — evaluate assertion 🎀

---

🌸 SYNOPSIS 🌸

1) assert(expression:long)

2) assert(expression:long,msg:string)

---

🦋 ARGUMENTS 🦋

• expression — the expression we're evaluating, like the vibe check itself 💅
• msg — the formatted message string, aka the little note it leaves you 📝

---

👑 DESCRIPTION 👑

1. This function checks the expression, and if that expression evaluates to zero it aborts the current running probe, no cap 😭. It uses error, and it can get caught by try{} catch{} — so your probe isn't necessarily doomed forever, it's giving catchable energy. A default message will be displayed. 🙈
2. Same situation, same energy: this function checks the expression and aborts the current running probe if the expression evaluates to zero. It uses error and may be caught by try{} catch{}. The difference? The specified message will be displayed instead of the default one. 🌈

Lowkey important: zero = abort, so if you're not about that probe-stopping life, wrap it up in try{} catch{}. ✨
