VFLUSHBUF(9)

🦋 NAME 🦋

okay bestie, welcome to VFLUSHBUF(9) from the Kernel Developer’s Manual ✨ this page is literally about vflushbuf — flush dirty vnode buffers to disk 💅 no cap.

---

🎀 SYNOPSIS 🎀

#include <sys/param.h>
#include <sys/vnode.h>

void
vflushbuf(struct vnode *vp, int sync);

🌸 DESCRIPTION 🌸

so vflushbuf() is the function that flushes all dirty buffers associated with the vnode vp to the disk 🫶.

here’s the vibe check on the sync argument:

• if sync is zero, the writes to the disk are asynchronous, and vflushbuf() returns immediately 🏃‍♀️💨
• otherwise, the writes are synchronous, and when vflushbuf() returns, all the disk blocks associated with the vnode have been properly synchronized with the in-core buffers ✅

that’s the whole plot, and it ate 💅
