/**
 * Structure describing a Win32 handle semaphore export operation.
 * 
 * 
Description

 * 
 * 
The properties of the handle returned depend on the value of {@code handleType}. See {@code VkExternalMemoryHandleTypeFlagBitsKHR} for a description of the properties of the defined external memory handle types.

 * 
 * 
Valid Usage

 * 
 * 
    
 * 
  • {@code handleType} must have been included in {@link VkExportMemoryAllocateInfoKHR}{@code ::handleTypes} when {@code memory} was created.
    • 
 * 
  • If {@code handleType} is defined as an NT handle, {@link KHRExternalMemoryWin32#vkGetMemoryWin32HandleKHR GetMemoryWin32HandleKHR} must be called no more than once for each valid unique combination of {@code memory} and {@code handleType}.
    • 
 * 
  • {@code handleType} must be defined as an NT handle or a global share handle.
    • 
 * 

 * 
 * 
Valid Usage (Implicit)

 * 
 * 
    
 * 
  • {@code sType} must be {@link KHRExternalMemoryWin32#VK_STRUCTURE_TYPE_MEMORY_GET_WIN32_HANDLE_INFO_KHR STRUCTURE_TYPE_MEMORY_GET_WIN32_HANDLE_INFO_KHR}
    • 
 * 
  • {@code pNext} must be {@code NULL}
    • 
 * 
  • {@code memory} must be a valid {@code VkDeviceMemory} handle
    • 
 * 
  • {@code handleType} must be a valid {@code VkExternalMemoryHandleTypeFlagBitsKHR} value
    • 
 * 

 * 
 *

Member documentation

 * 
 * 
    
 * 
  • {@code sType} – the type of this structure.
    • 
 * 
  • {@code pNext} – {@code NULL} or a pointer to an extension-specific structure.
    • 
 * 
  • {@code memory} – the memory object from which the handle will be exported.
    • 
 * 
  • {@code handleType} – the type of handle requested.
    •
