vkMapMemory2KHR

Alternatively, to retrieve a host virtual address pointer to a region of a mappable memory object, call:

VkResult vkMapMemory2KHR(
    VkDevice device,
    const VkMemoryMapInfoKHR* pMemoryMapInfo,
    void** ppData);

• device is the logical device that owns the memory.
• pMemoryMapInfo is a pointer to a VkMemoryMapInfoKHR structure describing parameters of the map.
• ppData is a pointer to a void * variable in which is returned a host-accessible pointer to the beginning of the mapped range. This pointer minus VkMemoryMapInfoKHR::offset must be aligned to at least VkPhysicalDeviceLimits::minMemoryMapAlignment.

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