💅 VOP_VPTOFH 💅

okay so bestie, welcome to the VOP_VPTOFH(9) page — section 9 of the kernel developer's manual, aka where the NFS server girlies hang out. buckle up, this one's short but iconic ✨

🌸 NAME 🌸

VOP_VPTOFH — turn a vnode into an NFS filehandle, no cap 🦋

✨ SYNOPSIS ✨

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

int
VOP_VPTOFH(struct vnode *vp, struct fid *fhp);

like, that's it. that's the whole signature. she's compact 💅

🎀 DESCRIPTION 🎀

so the NFS server literally uses this to create an opaque filehandle that uniquely identifies the file — and then an NFS client can use that filehandle later to access the file in the future. it's giving "save your progress" energy, fr fr 🔥

its arguments are:

  • vp — the vnode you're making a filehandle for. the main character, the one we're describing 👑
  • fhp — the return parameter for the filehandle. this is where the filehandle goes on its way back out 💖
