The DDHAL_DDMISCELLANEOUSCALLBACKSstructure contains miscellaneous callback functions used by the driver.
typedef struct _DDHAL_DDMISCELLANEOUSCALLBACKS { DWORD dwSize ; DWORD dwFlags ; LPDDHAL_GETAVAILDRIVERMEMORY GetAvailDriverMemory ; LPDDHAL_UPDATENONLOCALHEAP UpdateNonLocalHeap ; LPDDHAL_GETHEAPALIGNMENT GetHeapAlignment ; LPDDHALSURFCB_GETBLTSTATUS GetSysmemBltStatus ; } DDHAL_DDMISCELLANEOUSCALLBACKS, *LPDDHAL_DDMISCELLANEOUSCALLBACKS;
