stcrw_get_injected(9)

💅 stcrw_get_injected — from the Kernel API Manual, section 9, bestie 🎀

okay so picture this: you're deep in the s390 corner of the kernel, section 9 of the Kernel API Manual, and you just need to grab a CRW that somebody artificially shoved in there. That's the whole gig. Let's get into it ✨

---

🌸 NAME 🌸

stcrw_get_injected — literally just copy the artificial CRW data over into a CRW struct. that's it. that's the function. 🫶

---

✨ SYNOPSIS ✨

int stcrw_get_injected (struct crw *crw );

---

🎀 ARGUMENTS 🎀

• crw — the target CRW pointer. like, the place you want the data to land. she's the destination, the main character of the assignment 💅

---

🦋 DESCRIPTION 🦋

Retrieve an injected CRW data. Yes bestie, injected — this is the artificial stuff, not the real hardware moment.

Returns 0 on success 🎉, and 1 if no injected-CRW is available 😭 (nothing to grab, no cap).

The iconic part? The function reproduces the return code of the actual STCRW function. so the vibes stay consistent with the real thing — same return codes, no surprises, the way that consistency ate 🔥

ngl this one is short and sweet, which honestly is its own kind of slay 💜
