brelse(9r)
NAME
  brelse - General: Deallocates a buf structure

SYNOPSIS
  void brelse(
	  register 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 brelse routine deallocates a buf structure that was previously
  allocated by the getnewbuf routine. The buf structure contains information
  describing an I/O request. Device drivers call the brelse routine after the
  I/O request has completed to free the memory used by the buf structure.

RETURN VALUES
  None
