interrupt_destroy - destroys an interrupt object

## SYNOPSIS

<!-- Updated by update-docs-from-abigen, do not edit. -->

```
#include <zircon/syscalls.h>

zx_status_t zx_interrupt_destroy(zx_handle_t handle);
```

## DESCRIPTION

`zx_interrupt_destroy()` "destroys" an interrupt object, putting it in a state
where any [`zx_interrupt_wait()`] operations on it will return **ZX_ERR_CANCELED**,
and it is unbound from any ports it was bound to.

This provides a clean shut down mechanism.  Closing the last handle to the
interrupt object results in similar cancellation but could result in use-after-close
of the handle.

If the interrupt object is bound to a port when cancellation happens, if it
has not yet triggered, or it has triggered but the packet has not yet been
received by a caller of [`zx_port_wait()`], success is returned and any packets
in flight are removed.  Otherwise, **ZX_ERR_NOT_FOUND** is returned, indicating
that the packet has been read but the interrupt has not been re-armed by calling
[`zx_interrupt_ack()`].

## RETURN VALUE

`zx_interrupt_destroy()` returns **ZX_OK** on success. In the event
of failure, a negative error value is returned.

## ERRORS

**ZX_ERR_BAD_HANDLE** *handle* is an invalid handle.

**ZX_ERR_WRONG_TYPE** *handle* is not an interrupt object.

**ZX_ERR_NOT_FOUND**  *handle* was bound (and now no longer is) but was not
being waited for.

**ZX_ERR_ACCESS_DENIED** *handle* lacks **ZX_RIGHT_WRITE**.
