## C Specification

The VkPhysicalDeviceProtectedMemoryProperties structure is defined as:

// Provided by VK_VERSION_1_1
typedef struct VkPhysicalDeviceProtectedMemoryProperties {
VkStructureType    sType;
void*              pNext;
VkBool32           protectedNoFault;
} VkPhysicalDeviceProtectedMemoryProperties;

## Members

• sType is the type of this structure.

• pNext is NULL or a pointer to a structure extending this structure.

## Description

• protectedNoFault specifies how an implementation behaves when an application attempts to write to unprotected memory in a protected queue operation, read from protected memory in an unprotected queue operation, or perform a query in a protected queue operation. If this limit is VK_TRUE, such writes will be discarded or have undefined values written, reads and queries will return undefined values. If this limit is VK_FALSE, applications must not perform these operations. See https://www.khronos.org/registry/vulkan/specs/1.3-extensions/html/vkspec.html#memory-protected-access-rules for more information.

If the VkPhysicalDeviceProtectedMemoryProperties structure is included in the pNext chain of the VkPhysicalDeviceProperties2 structure passed to vkGetPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.

Valid Usage (Implicit)
• VUID-VkPhysicalDeviceProtectedMemoryProperties-sType-sType
sType must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_PROTECTED_MEMORY_PROPERTIES
