C Specification

The type of pfnInternalAllocation is:

typedef void (VKAPI_PTR *PFN_vkInternalAllocationNotification)(
    void*                                       pUserData,
    size_t                                      size,
    VkInternalAllocationType                    allocationType,
    VkSystemAllocationScope                     allocationScope);


  • pUserData is the value specified for VkAllocationCallbacks::pUserData in the allocator specified by the application.

  • size is the requested size of an allocation.

  • allocationType is a VkInternalAllocationType value specifying the requested type of an allocation.

  • allocationScope is a VkSystemAllocationScope value specifying the allocation scope of the lifetime of the allocation, as described here.
