C Specification

The VkMemoryGetWin32HandleInfoKHR structure is defined as:

// Provided by VK_KHR_external_memory_win32
typedef struct VkMemoryGetWin32HandleInfoKHR {
    VkStructureType                       sType;
    const void*                           pNext;
    VkDeviceMemory                        memory;
    VkExternalMemoryHandleTypeFlagBits    handleType;
} VkMemoryGetWin32HandleInfoKHR;

Members

  • sType is the type of this structure.

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

  • memory is the memory object from which the handle will be exported.

  • handleType is the type of handle requested.

Description

The properties of the handle returned depend on the value of handleType. See VkExternalMemoryHandleTypeFlagBits for a description of the properties of the defined external memory handle types.

Valid Usage
  • handleType must have been included in VkExportMemoryAllocateInfo::handleTypes when memory was created

  • If handleType is defined as an NT handle, vkGetMemoryWin32HandleKHR must be called no more than once for each valid unique combination of memory and handleType

  • handleType must be defined as an NT handle or a global share handle

Valid Usage (Implicit)
