FUNCTION::USER_STRING_NOFAULT(3stap)
β¨ NAME β¨
function::user_string_nofault β bestie, this one yoinks a string straight out of user space π
π SYNOPSIS π
user_string_nofault:string(addr:long)
π¦ ARGUMENTS π¦
addrβ the user space address you wanna grab that string from, fr fr. That's the spot, that's the vibe check location π
π DESCRIPTION π
Okay so here's the tea, bestie: this returns the null terminated C string sitting at a given user space memory address. Iconic. So useful. πΈ
But β and this is the part that matters β if the userspace data is not accessible, it hands you back the empty string. No crash, no drama, no chaos. Just a polite little nothing. πβ¨
Like, it literally says "nofault" in the name. It's not out here trying to start problems. It's giving safe-and-chill main character energy π
Heads up: when data isn't reachable, you get the empty string β not an error, not a partial string, not a spicy surprise. Empty. Periodt.
