MirOS Manual: getnewvnode(9)

GETNEWVNODE(9)                BSD Kernel Manual                 GETNEWVNODE(9)


     getnewvnode - get a new vnode


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

     getnewvnode(enum vtagtype tag, struct mount *mp,
             int (**vops) __P((void *)), struct vnode **vpp);


     The getnewvnode() function initializes a new vnode, assigning it the
     vnode operations passed in vops. It will have its v_tag field set to tag
     and be placed in the mount queue for the mount point represented by mp.

     The vnode is either freshly allocated, taken from the free list or taken
     from the hold list. If there are no vnodes on the free list, half the
     time a vnode referencing buffers will be taken from the hold list, other-
     wise it will be freshly allocated.

     The arguments to getnewvnode() are:

     tag       The file system type.

     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.


     getnewvnode() returns 0 on success, or ENFILE if the vnode table is full.
