memory_contains(9)

💖 NAME 💖

okay so bestie, this is memory_contains(9) from the Kernel API Manual, and it literally checks if an object is contained within a memory region. That's the whole vibe. ✨

🎀 SYNOPSIS 🎀

bool memory_contains (void *begin , void *end , void *virt , size_t size
);

🌸 ARGUMENTS 🌸

• begin — virtual address of the beginning of the memory region. Like, where the region starts, bestie. 🫶
• end — virtual address of the end of the memory region. The finish line. 🏁
• virt — virtual address of the memory object. The thing we're checking on. 👀
• size — size of the memory object. Gotta know how big it is. 💅

🌈 RETURN 🌈

It returns true if the object specified by virt and size is entirely contained within the memory region defined by begin and end — and false otherwise. No cap, that's the whole return story. 💖
