GETNEWVNODE(9)                    BSD Kernel Developer's Manual                    GETNEWVNODE(9)

NAME
     getnewvnode — get a new vnode

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

     int
     getnewvnode(const char *tag, struct mount *mp, vop_t **vops, struct vnode **vpp);

DESCRIPTION
     The getnewvnode() function initializes a new vnode, assigning it the vnode operations passed
     in vops.  The vnode is either freshly allocated, or taken from the head of the free list
     depending on the number of vnodes already in the system.

     The arguments to getnewvnode() are:

     tag   The file system type string.  This field should only be referenced for debugging or
           for userland utilities.

     mp    The mount point to add the new vnode to.

     vops  The vnode operations to assign to the new vnode.

     vpp   Points to the new vnode upon successful completion.

RETURN VALUES
     getnewvnode() returns 0 on success.  There are currently no failure conditions - that do not
     result in a panic.
