Destroys an interrupt object.
#include <zircon/syscalls.h> zx_status_t zx_interrupt_destroy(zx_handle_t handle);
zx_interrupt_destroy() "destroys" an interrupt object, putting it in a state
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_destroy() returns ZX_OK on success. In the event
of failure, a negative error value is returned.
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.
