SET(9)

✨ SET(9) — primitive bit macros ✨

from the Kernel Developer's Manual, bestie 🫶

🌸 NAME 🌸

SET — primitive bit macros 💅

🎀 SYNOPSIS 🎀

#include <sys/types.h>

void
SET(val, x);

int
ISSET(val, x);

void
CLR(val, x);

🦋 DESCRIPTION 🦋

okay so these macros define three standard bit operations, fr fr:

1. SET() sets the set bits from x in val — iconic behavior honestly ✨
2. CLR() clears the set bits from x in val — bye bye bits 💅
3. ISSET() returns true if any of the set bits from x are set in val — the vibe check 🔥

🔥 SEE ALSO 🔥

• bits(3)

💀 BUGS 💀

The rationale is to provide clarity in the source code, but arguably these operations are clear enough without the use of the macros. Like… no cap? 🙈
