vkUnmapMemory2

Alternatively, to unmap a memory object once host access to it is no longer needed by the application, call:

VkResult vkUnmapMemory2KHR(
    VkDevice device,
    const VkMemoryUnmapInfo* pMemoryUnmapInfo);

• device is the logical device that owns the memory.
• pMemoryUnmapInfo is a pointer to a VkMemoryUnmapInfo structure describing parameters of the unmap.

This function behaves identically to vkUnmapMemory except that it gets its parameters via an extensible structure pointer rather than directly as function arguments.
