ring_buffer_record_is_on(9)

📦 version 7.3.1, in nixpkgs unstable

🦋 NAME 🦋

okay so bestie, this is ring_buffer_record_is_on(9) from the Kernel API Manual, and it’s here to answer one very specific question: return true if the ring buffer can write. That’s the whole name, that’s the whole mission. 💖

✨ SYNOPSIS ✨

bool ring_buffer_record_is_on (struct trace_buffer *buffer );

🎀 ARGUMENTS 🎀

  • buffer — the ring buffer you’re checking to see if write is enabled. Like, “is this one accepting writes or not?” energy. 🫶

💖 DESCRIPTION 💖

Returns true if the ring buffer is in a state that it accepts writes. That’s it — a little boolean vibe check for the ring buffer, no extra lore. ✨
