VOP_PRINT(9)

πŸ’– VOP_PRINT β€” bestie's guide to printing debug info πŸ’–

okay so this is the VOP_PRINT(9) page, aka the kernel developer's manual entry for a little function that just... prints stuff. for debugging. that's the whole job. and honestly? iconic of it.


✨ NAME ✨

VOP_PRINT β€” print debugging information

like. it prints debugging information. no cap. that's it, that's the function. 🫢


🌸 SYNOPSIS 🌸

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

int
VOP_PRINT(struct vnode *vp);

so you gotta pull in both headers first β€” <sys/param.h> and <sys/vnode.h> β€” and then boom, VOP_PRINT is yours. it takes one struct vnode * and hands you back an int. simple. clean. ate. πŸ’…


πŸ¦‹ DESCRIPTION πŸ¦‹

the arguments are:

  • vp β€” the vnode to print. that's the one. the only one. you hand it a vnode and it prints it. give it literally anything else and that's a you problem, bestie. 😭

πŸ‘‘ RETURN VALUES πŸ‘‘

Zero is returned on success, otherwise an error is returned. so like β€” 0 means we slayed, anything else means something went sideways. always check your return values, fr fr. ✨

no notes, no drama, just a vnode getting printed. main character energy from a debug function, honestly. πŸ’œ

and that's the whole vibe check! this one's from the Debian crew, dated July 24, 1996 β€” yeah, 1996, it's vintage, it's a classic, it's giving old money πŸ’€πŸ’– β€” and it lives in the Kernel Developer's Manual. bye bestie, go print a vnode! 🧚🌸
