vkGetMemoryHostPointerPropertiesEXT(3)

Name

vkGetMemoryHostPointerPropertiesEXT - Get properties of external memory host pointer

C Specification

To determine the correct parameters to use when importing host pointers, call:

// Provided by VK_EXT_external_memory_host
VkResult vkGetMemoryHostPointerPropertiesEXT(
    VkDevice                                    device,
    VkExternalMemoryHandleTypeFlagBits          handleType,
    const void*                                 pHostPointer,
    VkMemoryHostPointerPropertiesEXT*           pMemoryHostPointerProperties);

Parameters

  • device is the logical device that will be importing pHostPointer.

  • handleType is a VkExternalMemoryHandleTypeFlagBits value specifying the type of the handle pHostPointer.

  • pHostPointer is the host pointer to import from.

  • pMemoryHostPointerProperties is a pointer to a VkMemoryHostPointerPropertiesEXT structure in which the host pointer properties are returned.
