biodone(9r)
NAME
  biodone - General: Indicates that block I/O is complete

SYNOPSIS
  void biodone(
	  struct buf *bp );

ARGUMENTS
  bp  Specifies a pointer to a buf structure.  This structure contains
      information such as the binary status flags, the major/minor device
      numbers, and the address of the associated buffer. This buffer is
      always a special buffer header owned exclusively by the device for
      handling I/O requests.

DESCRIPTION
  The biodone routine is called after an I/O operation to mark the buf
  structure as completed. It sets the b_flags member to B_SWAP, B_UBC, or
  B_ASYNC to indicate the type of I/O operation that has completed. Other
  members may be set as well, depending on the type of I/O operation.

CAUTIONS
  The routine panics if the buf structure is NULL.

RETURN VALUES
  None
