50.Sh DESCRIPTION
51These entry points create a new file, socket, fifo, device, directory or symlink
52in a given directory.
53.Pp
54The arguments are:
55.Bl -tag -width target
56.It Fa dvp
57the locked vnode of the directory
58.It Fa vpp
59the address of a variable where the resulting locked vnode should be stored
60.It Fa cnp
61the pathname component created
62.It Fa vap
63the attributes that the new object should be created with
64.It Fa target
65the pathname of the target of the symlink
66.El
67.Pp
68These entry points are called after
69.Xr VOP_OLD_LOOKUP 9
70when an object is being created.
71If an error is detected when creating the file,
72then this memory will be freed.
73If the file is created successfully, then it will be freed.
74.Sh LOCKS
75The directory,
76.Fa dvp
77will be locked on entry and must remain locked on return.
78If the call is successful, the new object will be returned locked.
79.Sh RETURN VALUES
80If successful, the vnode for the new object is placed in
81.Fa *vpp
82and zero is returned.  Otherwise, an appropriate error is returned.
83.Sh ERRORS
84.Bl -tag -width Er
85.It Bq Er ENOSPC
86The filesystem is full.
87.It Bq Er EDQUOT
