setdisklabel(9r)
NAME
  setdisklabel - Disk: Sets a disk label

SYNOPSIS
  int setdisklabel(
	  register struct disklabel *old_lp,
	  register struct disklabel *new_lp,
	  u_int openmask );

ARGUMENTS
  old_lp
      Specifies the old disklabel structure for the device.

  new_lp
      Specifies the new disklabel structure that contains the user's changes.

  openmask
      Specifies a bit mask in which each set bit represents an open partition
      and each cleared bit represents a partition that is not open.

DESCRIPTION
  The setdisklabel interface sets the in-memory copy of the disklabel
  structure to the new values specified by the user.

  The DIOCWDINFO and DIOCSDINFO ioctl commands call setdisklabel to set the
  in-memory disk label and to check the validity of the new settings.

RETURN VALUES
  Upon successful completion, setdisklabel returns the value zero (0).
  Otherwise, it returns EBUSY if:

    ·  The number of partitions in the new disklabel is less than the number
       of open partitions

    ·  A partition offset in the new disklabel is not equal to the
       corresponding partition offset in the old disklabel

    ·  The size of a new partition in the new disklabel is less than the size
       of the corresponding partition in the old disklabel
