class GuestBellTrapBase
Defined at line 24 of file ../../sdk/lib/async/include/lib/async/cpp/trap.h
Holds context for a bell trap and its handler.
After successfully posting setting the trap, the client is responsible for retaining
the structure in memory (and unmodified) until the guest has been destroyed or the
dispatcher shuts down. There is no way to cancel a trap which has been set.
Concrete implementations: |async::GuestBellTrap|, |async::GuestBellTrapMethod|.
Please do not create subclasses of GuestBellTrapBase outside of this library.
Public Methods
zx_status_t SetTrap (async_dispatcher_t * dispatcher, const zx::guest & guest, zx_vaddr_t addr, size_t length)Sets a bell trap in the guest to be handled asynchronously via a handler.
|guest| is the handle of the guest the trap will be set on.
|addr| is the base address for the trap in the guest's physical address space.
|length| is the size of the trap in the guest's physical address space.
Returns |ZX_OK| if the trap was successfully set.
Returns |ZX_ERR_ACCESS_DENIED| if the guest does not have |ZX_RIGHT_WRITE|.
Returns |ZX_ERR_ALREADY_EXISTS| if a bell trap with the same |addr| exists.
Returns |ZX_ERR_INVALID_ARGS| if |addr| or |length| are invalid.
Returns |ZX_ERR_OUT_OF_RANGE| if |addr| or |length| are out of range of the
address space.
Returns |ZX_ERR_WRONG_TYPE| if |guest| is not a handle to a guest.
Returns |ZX_ERR_BAD_STATE| if the dispatcher is shutting down.
Returns |ZX_ERR_NOT_SUPPORTED| if not supported by the dispatcher.
This operation is thread-safe.
