C Specification

The VkMemoryGetWin32HandleInfoKHR structure is defined as:

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


  • sType is the type of this structure.

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

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

  • handleType is the type of handle requested.


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)

  • pNext must be NULL

  • memory must be a valid VkDeviceMemory handle

  • handleType must be a valid VkExternalMemoryHandleTypeFlagBits value
