struct EventType [src]

Fields

lo_context: u8 = 0

wait: bool = falseIf an event of this type is not already in the signaled state, then the event’s NotificationFunction will be queued at the event’s NotifyTpl whenever the event is being waited on via EFI_BOOT_SERVICES.WaitForEvent() or EFI_BOOT_SERVICES.CheckEvent() .

signal: bool = falseThe event’s NotifyFunction is queued whenever the event is signaled.

hi_context: u20 = 0

runtime: bool = falseThe event is allocated from runtime memory. If an event is to be signaled after the call to EFI_BOOT_SERVICES.ExitBootServices() the event’s data structure and notification function need to be allocated from runtime memory.

timer: bool = false
