If the call is successful, the new object will be returned locked. .Sh RETURN VALUES If successful, the vnode for the new object is placed in .Fa *vpp and zero is returned. Otherwise, an appropriate error is returned. .Sh ERRORS .Bl -tag -width Er .It Bq Er ENOSPC The file system is full. .It Bq Er EDQUOT The user's file system space or inode quota would be exceeded. .El .Sh SEE ALSO .Xr vnode 9 , .Xr VOP_LOOKUP 9 .Sh HISTORY The function .Nm appeared in .Bx 4.3 . .Sh AUTHORS This manual page was written by .An Doug Rabson .
