## C Specification

The VkPhysicalDeviceMaintenance3Properties structure is defined as:

typedef struct VkPhysicalDeviceMaintenance3Properties {
VkStructureType    sType;
void*              pNext;
uint32_t           maxPerSetDescriptors;
VkDeviceSize       maxMemoryAllocationSize;
} VkPhysicalDeviceMaintenance3Properties;

or the equivalent

typedef VkPhysicalDeviceMaintenance3Properties VkPhysicalDeviceMaintenance3PropertiesKHR;

## Members

The members of the VkPhysicalDeviceMaintenance3Properties structure describe the following implementation-dependent limits:

## Description

• sType is the type of this structure.

• pNext is NULL or a pointer to an extension-specific structure.

• maxPerSetDescriptors is a maximum number of descriptors (summed over all descriptor types) in a single descriptor set that is guaranteed to satisfy any implementation-dependent constraints on the size of a descriptor set itself. Applications can query whether a descriptor set that goes beyond this limit is supported using vkGetDescriptorSetLayoutSupport.

• maxMemoryAllocationSize is the maximum size of a memory allocation that can be created, even if there is more space available in the heap.

If the VkPhysicalDeviceMaintenance3Properties structure is included in the pNext chain of VkPhysicalDeviceProperties2, it is filled with the implementation-dependent limits.

Valid Usage (Implicit)
• sType must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_MAINTENANCE_3_PROPERTIES
