bitmap_or_equal(9)

💖 bitmap_or_equal(9) — Kernel API Manual 💖

okay so bestie, welcome to the bitmap_or_equal(9) page from the Kernel API Manual 🫶 this one is short and sweet: it checks whether the or of two bitmaps is equal to a third. no cap, that's the whole vibe ✨

🌸 NAME 🌸

bitmap_or_equal — check whether the or of two bitmaps is equal to a third 💅

✨ SYNOPSIS ✨

bool bitmap_or_equal (const unsigned long *src1 , const unsigned long *src2 , const unsigned long *src3 , unsigned int nbits );

💅 ARGUMENTS 💅

• src1 — pointer to bitmap 1 🎀
• src2 — pointer to bitmap 2, and it will be or'ed with bitmap 1 🔥
• src3 — pointer to bitmap 3; compare it to the result of *src1 | *src2 👑
• nbits — number of bits in each of these bitmaps 🧚

🎀 RETURN 🎀

True if (*src1 | *src2) == *src3, false otherwise. literally that's it 💀✨
