public class VkMemoryAllocateInfo
extends org.lwjgl.system.Struct
implements org.lwjgl.system.NativeResource
```
Structure containing parameters of a memory allocation.
Description

The internal data of an allocated device memory object must include a reference to implementation-specific resources, referred to as the memory object’s payload. Applications can also import and export that internal data to and from device memory objects to share data between Vulkan instances and other compatible APIs. A VkMemoryAllocateInfo structure defines a memory import operation if its pNext chain includes one of the following structures:
- VkImportMemoryWin32HandleInfoKHR with a non-zero handleType value
- VkImportMemoryFdInfoKHR with a non-zero handleType value
- VkImportMemoryHostPointerInfoEXT with a non-zero handleType value
If the parameters define an import operation and the external handle type is EXTERNAL_MEMORY_HANDLE_TYPE_D3D11_TEXTURE_BIT, EXTERNAL_MEMORY_HANDLE_TYPE_D3D11_TEXTURE_KMT_BIT, or EXTERNAL_MEMORY_HANDLE_TYPE_D3D12_RESOURCE_BIT, allocationSize is ignored. The implementation must query the size of these allocations from the OS.

Whether device memory objects constructed via a memory import operation hold a reference to their payload depends on the properties of the handle type used to perform the import, as defined below for each valid handle type. Importing memory must not modify the content of the memory. Implementations must ensure that importing memory does not enable the importing Vulkan instance to access any memory or resources in other Vulkan instances other than that corresponding to the memory object imported. Implementations must also ensure accessing imported memory which has not been initialized does not allow the importing Vulkan instance to obtain data from the exporting Vulkan instance or vice-versa.

Note

How exported and imported memory is isolated is left to the implementation, but applications should be aware that such isolation may prevent implementations from placing multiple exportable memory objects in the same physical or virtual page. Hence, applications should avoid creating many small external memory objects whenever possible.

Importing memory must not increase overall heap usage within a system. However, it must affect the following per-process values:
- VkPhysicalDeviceMaintenance3Properties::maxMemoryAllocationCount
- VkPhysicalDeviceMemoryBudgetPropertiesEXT::heapUsage
When performing a memory import operation, it is the responsibility of the application to ensure the external handles and their associated payloads meet all valid usage requirements. However, implementations must perform sufficient validation of external handles and payloads to ensure that the operation results in a valid memory object which will not cause program termination, device loss, queue stalls, or corruption of other resources when used as allowed according to its allocation parameters. If the external handle provided does not meet these requirements, the implementation must fail the memory import operation with the error code ERROR_INVALID_EXTERNAL_HANDLE.

Valid Usage
- allocationSize must be greater than 0
- If the pNext chain includes a VkExportMemoryAllocateInfo structure, and any of the handle types specified in VkExportMemoryAllocateInfo::handleTypes require a dedicated allocation, as reported by GetPhysicalDeviceImageFormatProperties2 in VkExternalImageFormatProperties::externalMemoryProperties.externalMemoryFeatures or VkExternalBufferProperties::externalMemoryProperties.externalMemoryFeatures, the pNext chain must include a VkMemoryDedicatedAllocateInfo or VkDedicatedAllocationMemoryAllocateInfoNV structure with either its image or buffer member set to a value other than NULL_HANDLE
- If the pNext chain includes a VkExportMemoryAllocateInfo structure, it must not include a VkExportMemoryAllocateInfoNV or VkExportMemoryWin32HandleInfoNV structure
- If the pNext chain includes a VkImportMemoryWin32HandleInfoKHR structure, it must not include a VkImportMemoryWin32HandleInfoNV structure
- If the parameters define an import operation, the external handle specified was created by the Vulkan API, and the external handle type is EXTERNAL_MEMORY_HANDLE_TYPE_OPAQUE_FD_BIT, then the values of allocationSize and memoryTypeIndex must match those specified when the payload being imported was created
- If the parameters define an import operation and the external handle specified was created by the Vulkan API, the device mask specified by VkMemoryAllocateFlagsInfo must match the mask specified when the payload being imported was allocated
- If the parameters define an import operation and the external handle specified was created by the Vulkan API, the list of physical devices that comprise the logical device passed to AllocateMemory must match the list of physical devices that comprise the logical device on which the payload was originally allocated
- If the parameters define an import operation and the external handle is an NT handle or a global share handle created outside of the Vulkan API, the value of memoryTypeIndex must be one of those returned by GetMemoryWin32HandlePropertiesKHR
- If the parameters define an import operation, the external handle was created by the Vulkan API, and the external handle type is EXTERNAL_MEMORY_HANDLE_TYPE_OPAQUE_WIN32_BIT or EXTERNAL_MEMORY_HANDLE_TYPE_OPAQUE_WIN32_KMT_BIT, then the values of allocationSize and memoryTypeIndex must match those specified when the payload being imported was created
- If the parameters define an import operation and the external handle type is EXTERNAL_MEMORY_HANDLE_TYPE_D3D12_HEAP_BIT, allocationSize must match the size specified when creating the Direct3D 12 heap from which the payload was extracted
- If the parameters define an import operation and the external handle is a POSIX file descriptor created outside of the Vulkan API, the value of memoryTypeIndex must be one of those returned by GetMemoryFdPropertiesKHR
- If the protected memory feature is not enabled, the VkMemoryAllocateInfo::memoryTypeIndex must not indicate a memory type that reports MEMORY_PROPERTY_PROTECTED_BIT
- If the parameters define an import operation and the external handle is a host pointer, the value of memoryTypeIndex must be one of those returned by GetMemoryHostPointerPropertiesEXT
- If the parameters define an import operation and the external handle is a host pointer, allocationSize must be an integer multiple of VkPhysicalDeviceExternalMemoryHostPropertiesEXT::minImportedHostPointerAlignment
- If the parameters define an import operation and the external handle is a host pointer, the pNext chain must not include a VkDedicatedAllocationMemoryAllocateInfoNV structure with either its image or buffer field set to a value other than NULL_HANDLE
- If the parameters define an import operation and the external handle is a host pointer, the pNext chain must not include a VkMemoryDedicatedAllocateInfo structure with either its image or buffer field set to a value other than NULL_HANDLE
- If VkMemoryOpaqueCaptureAddressAllocateInfo::opaqueCaptureAddress is not zero, VkMemoryAllocateFlagsInfo::flags must include MEMORY_ALLOCATE_DEVICE_ADDRESS_CAPTURE_REPLAY_BIT
- If VkMemoryAllocateFlagsInfo::flags includes MEMORY_ALLOCATE_DEVICE_ADDRESS_CAPTURE_REPLAY_BIT, the bufferDeviceAddressCaptureReplay feature must be enabled
- If VkMemoryAllocateFlagsInfo::flags includes MEMORY_ALLOCATE_DEVICE_ADDRESS_BIT, the bufferDeviceAddress feature must be enabled
- If the pNext chain includes a VkImportMemoryHostPointerInfoEXT structure, VkMemoryOpaqueCaptureAddressAllocateInfo::opaqueCaptureAddress must be zero
- If the parameters define an import operation, VkMemoryOpaqueCaptureAddressAllocateInfo::opaqueCaptureAddress must be zero
Valid Usage (Implicit)
- sType must be STRUCTURE_TYPE_MEMORY_ALLOCATE_INFO
- Each pNext member of any structure (including this one) in the pNext chain must be either NULL or a pointer to a valid instance of VkDedicatedAllocationMemoryAllocateInfoNV, VkExportMemoryAllocateInfo, VkExportMemoryAllocateInfoNV, VkExportMemoryWin32HandleInfoKHR, VkExportMemoryWin32HandleInfoNV, VkImportMemoryFdInfoKHR, VkImportMemoryHostPointerInfoEXT, VkImportMemoryWin32HandleInfoKHR, VkImportMemoryWin32HandleInfoNV, VkMemoryAllocateFlagsInfo, VkMemoryDedicatedAllocateInfo, VkMemoryOpaqueCaptureAddressAllocateInfo, or VkMemoryPriorityAllocateInfoEXT
- The sType value of each struct in the pNext chain must be unique
