Package org.lwjgl.vulkan

Class KHRZeroInitializeWorkgroupMemory

java.lang.Object
org.lwjgl.vulkan.KHRZeroInitializeWorkgroupMemory
public final class KHRZeroInitializeWorkgroupMemory extends Object
This extension allows the use of a null constant initializer on shader Workgroup memory variables, allowing implementations to expose any special hardware or instructions they may have. Zero initialization is commonly used by applications running untrusted content (e.g. web browsers) as way of defeating memory-scraping attacks.
Promotion to Vulkan 1.3

Vulkan APIs in this extension are included in core Vulkan 1.3, with the KHR suffix omitted. External interactions defined by this extension, such as SPIR-V token names, retain their original names. The original Vulkan API names are still available as aliases of the core functionality.
