/**
* Structure describing a POSIX FD semaphore export operation.
*
* Description
*
* The properties of the file descriptor exported depend on the value of {@code handleType}. See {@code VkExternalMemoryHandleTypeFlagBitsKHR} for a description of the properties of the defined external memory handle types.
*
* Note
*
* The size of the exported file may be larger than the size requested by {@link VkMemoryAllocateInfo}::allocationSize. If {@code handleType} is {@link EXTExternalMemoryDmaBuf#VK_EXTERNAL_MEMORY_HANDLE_TYPE_DMA_BUF_BIT_EXT EXTERNAL_MEMORY_HANDLE_TYPE_DMA_BUF_BIT_EXT}, then the application can query the file's actual size with link:man:lseek(2)[lseek(2)].
*
*
* Valid Usage
*
*
* - {@code handleType} must have been included in {@link VkExportMemoryAllocateInfoKHR}{@code ::handleTypes} when {@code memory} was created.
* - {@code handleType} must be defined as a POSIX file descriptor handle.
*
*
* Valid Usage (Implicit)
*
*
* - {@code sType} must be {@link KHRExternalMemoryFd#VK_STRUCTURE_TYPE_MEMORY_GET_FD_INFO_KHR STRUCTURE_TYPE_MEMORY_GET_FD_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
*
*
* See Also
*
* {@link KHRExternalMemoryFd#vkGetMemoryFdKHR GetMemoryFdKHR}
*
* 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.
*
*
* Layout
*
*
* struct VkMemoryGetFdInfoKHR {
* VkStructureType sType;
* const void * pNext;
* VkDeviceMemory memory;
* VkExternalMemoryHandleTypeFlagBitsKHR handleType;
* }The created instance holds a strong reference to the container object.
