NAME

       VOP_CREATE, VOP_MKNOD, VOP_MKDIR, VOP_SYMLINK — create a file, socket, fifo, device, directory or symlink

SYNOPSIS

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

       int
       VOP_CREATE(struct vnode *dvp, struct vnode **vpp, struct componentname *cnp, struct vattr *vap);

       int
       VOP_MKNOD(struct vnode *dvp, struct vnode **vpp, struct componentname *cnp, struct vattr *vap);

       int
       VOP_MKDIR(struct vnode *dvp, struct vnode **vpp, struct componentname *cnp, struct vattr *vap);

       int
       VOP_SYMLINK(struct  vnode  *dvp,  struct  vnode  **vpp,  struct  componentname  *cnp,  struct vattr *vap,
           char *target);

DESCRIPTION

       These entry points create a new file, socket, fifo, device, directory or symlink in a given directory.

       The arguments are:

       dvp     The locked vnode of the directory.

       vpp     The address of a variable where the resulting locked vnode should be stored.

       cnp     The pathname component created.

       vap     The attributes that the new object should be created with.

       target  The pathname of the target of the symlink.

       These entry points are called after VOP_LOOKUP(9) when an object is being created.

LOCKS

       The directory, dvp will be locked on entry and must remain locked on return.  If the call is  successful,
       the new object will be returned locked.

RETURN VALUES

       If  successful,  the  vnode  for  the  new  object is placed in *vpp and zero is returned.  Otherwise, an
       appropriate error is returned.

ERRORS

       [ENOSPC]           The file system is full.

       [EDQUOT]           The user's file system space or inode quota would be exceeded.
