FUNCTION::KERNEL_CHAR(3stap)

💖 function::kernel_char — the 3stap manual, bestie edition 💖

okay so real talk, this is a page from the SystemTap Tapset Reference (that's the 3stap manual section, iykyk) and it's about a lil function that goes and grabs one single char out of kernel memory. tiny job. iconic execution. let's get into it ✨

---

🌸 NAME 🌸

function::kernel_char — retrieves a char value stored in kernel memory

like. that's it. that's the whole gig. one character. she's small but she's everything 💅

---

✨ SYNOPSIS ✨

kernel_char:long(addr:long)

look at her. one argument. no drama. slay 🎀

---

🦋 ARGUMENTS 🦋

• addr — the kernel address to retrieve the char from. that's the spot in kernel memory you're pointing at, bestie, and she will go get the char that lives there 🫶

---

💜 DESCRIPTION 💜

okay so here's the vibe: kernel_char returns the char value from a given kernel memory address. you give her an address, she hands you back a char. simple. clean. main character energy fr fr 👑

but — and this is the part where we get serious for one sec — she reports an error when reading from the given address fails. so if that read doesn't work out? she's not gonna quietly pretend everything's fine. she's gonna tell you. no cap. 😭

💀 do not expect a silent failure here. if the read from that address doesn't go through, an error gets reported. periodt.
