VKEVENTGET

VKEVENTGET is a term used in some Vulkan-focused codebases and engine wrappers to refer to a wrapper-style function or macro that retrieves the current status of a synchronization primitive known as a VkEvent. A VkEvent is a host-visible object used to synchronize CPU and GPU work in Vulkan applications, capable of being signaled or unsignaled to coordinate operations.

In typical implementations, VKEVENTGET provides a convenient means to check whether a given event is signaled without invoking the core Vulkan calls directly. The exact signature and return type can vary by library, but the intention is to report whether the event is in a signaled state and may return a boolean or a VkResult-like value. Many wrappers map VKEVENTGET to an underlying Vulkan call such as vkGetEventStatus, returning information about the event’s state.

Relationship to Vulkan: In the core Vulkan API, the standard function vkGetEventStatus returns VK_SUCCESS when the event is signaled and VK_NOT_READY if it is not, with other VkResult codes indicating errors. VKEVENTGET is not part of the official Vulkan specification but is a wrapper abstraction found in some engines to simplify event polling and synchronization logic for developers.

Usage considerations: Because VKEVENTGET is wrapper-specific, its exact behavior can differ across frameworks. Developers should consult their specific library’s documentation to understand the expected return values, threading implications, and how it interacts with other synchronization primitives such as vkSetEvent and vkResetEvent.
