pt_range_slice(9)

💅 NAME — pt_range_slice(9)

Okay so this is the manual page for pt_range_slice from the Kernel API Manual, section 9, and it's literally about returning a range that spans indexes. Bestie, it's giving “slice the current table level” energy. Periodt.

✨ SYNOPSIS ✨

Here's the exact signature, no edits, no cap:

struct pt_range pt_range_slice (const struct pt_state *pts , unsigned
       int start_index , unsigned int end_index );

🎀 ARGUMENTS 🎀

• pts — Iteration State. Yep, the iteration state itself, bestie.
• start_index — starting index within pts. That's where the slice starts, fr fr.
• end_index — ending index within pts. That's where it ends. Slay.

💖 DESCRIPTION 💖

Okay so pt_range_slice creates a range that spans an index range of the current table level that pt_state points at. Lowkey it's slicing a chunk of the current table level by index and handing it back as a struct pt_range. That's the whole vibe. ✨
