memory_intersects(9)

🎀 NAME 🎀

okay so bestie, this is memory_intersects(9) from the Kernel API Manual — the function that checks if the region occupied by an object intersects with another memory region. short, iconic, and lowkey exactly what it says. 💅✨

✨ SYNOPSIS ✨

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

🫶 ARGUMENTS 🫶

here's the cast, no cap:

• begin — virtual address of the beginning of the memory region 🎀
• end — virtual address of the end of the memory region 🌸
• virt — virtual address of the memory object 🦋
• size — size of the memory object ✨

💖 RETURN 💖

this returns true if the object's memory region, specified by virt and size, intersects with the region specified by begin and end — and false otherwise. literally that simple, periodt. 👑🔥
