Wait for an interrupt.
#include <zircon/syscalls.h> zx_status_t zx_interrupt_wait(zx_handle_t handle, zx_time_t* out_timestamp);
zx_interrupt_wait()
is a blocking syscall which causes the caller to wait until an interrupt is triggered. It can only be used on interrupt objects that have not been bound to a port with zx_interrupt_bind()
It also, before the waiting begins, will acknowledge the interrupt object, as if zx_interrupt_ack()
were called on it.
The wait may be aborted with zx_interrupt_destroy()
or by closing the handle.
handle must be of type ZX_OBJ_TYPE_INTERRUPT and have ZX_RIGHT_WAIT.
zx_interrupt_wait()
returns ZX_OK on success, and out_timestamp, if non-NULL, returns the timestamp of when the interrupt was triggered (relative to ZX_CLOCK_MONOTONIC)
ZX_ERR_BAD_HANDLE handle is an invalid handle.
ZX_ERR_WRONG_TYPE handle is not a handle to an interrupt object.
ZX_ERR_BAD_STATE the interrupt object is bound to a port.
ZX_ERR_ACCESS_DENIED handle lacks ZX_RIGHT_WAIT.
ZX_ERR_CANCELED handle was closed while waiting or zx_interrupt_destroy()
was called on it.
ZX_ERR_INVALID_ARGS the out_timestamp parameter is an invalid pointer.
