vba_clear_irq(9r)
NAME
  vba_clear_irq - VMEbus: Removes a posted interrupt request

SYNOPSIS
  boolean_t vba_clear_irq(
	  struct controller *ctlr,
	  unsigned int irq,
	  unsigned int status_ID );

ARGUMENTS
  ctlr
      Specifies a pointer to the VMEbus device's controller data structure.

  irq Specifies the VMEbus interrupt request line on which you want to remove
      the previously posted interrupt.

  status_ID
      Specifies an ID that must match the status ID that you specified in the
      call to vba_post_irq(). If the ID is zero (0) or the ID matches the
      currently posted status ID, vba_clear_irq() removes the request at the
      specified interrupt request line.

DESCRIPTION
  The vba_clear_irq() routine removes an interrupt request that was posted on
  a previous call to vba_post_irq().  If you pass a status_ID, it must match
  the value you passed to vba_post_irq(). Otherwise, vba_clear_irq() returns
  an error. If you pass the value zero (0) to status_ID, then vba_clear_irq()
  removes any interrupt request on the specified interrupt request line.

RETURN VALUES
  The vba_clear_irq() routine returns one of the following values:

  __________________________________________________________________
  Value	  Meaning
  __________________________________________________________________
  TRUE

	  The vba_clear_irq() routine clears the posted interrupt on
	  the specified interrupt request line.

	  This VMEbus adapter provides no support for a
	  vba_clear_irq() routine.
  FALSE

	  The vba_clear_irq() routine failed to clear the posted
	  interrupt on the specified interrupt request line.

	  The status_ID you specified does not match the posted
	  interrupt on the specified interrupt request line.
