C Specification

The VkPhysicalDeviceExternalMemoryHostPropertiesEXT structure is defined as:

// Provided by VK_EXT_external_memory_host
typedef struct VkPhysicalDeviceExternalMemoryHostPropertiesEXT {
    VkStructureType    sType;
    void*              pNext;
    VkDeviceSize       minImportedHostPointerAlignment;
} VkPhysicalDeviceExternalMemoryHostPropertiesEXT;


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


  • sType is the type of this structure.

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

  • minImportedHostPointerAlignment is the minimum required alignment, in bytes, for the base address and size of host pointers that can be imported to a Vulkan memory object.

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

Valid Usage (Implicit)
  • VUID-VkPhysicalDeviceExternalMemoryHostPropertiesEXT-sType-sType
