upper_32_bits(9)

💅 upper_32_bits — Kernel API Manual energy ✨

🏷️ NAME

upper_32_bits — return bits 32-63 of a number, no cap 💖

📜 SYNOPSIS

upper_32_bits (n );

🎀 ARGUMENTS

• n — the number we're accessing, literally the thing you're pulling bits from 🫶

💖 DESCRIPTION

It's a basic shift-right of a 64- or 32-bit quantity. Bestie, use this to suppress the "right shift count >= width of type" warning when that quantity is 32-bits. Periodt ✨

Lowkey important: this is the move for that exact warning vibe, not a random flex 💅
