D3DKMT_QUERY_PHYSICAL_ADAPTER_PNP_KEY structure (d3dkmthk.h)
The D3DKMT_QUERY_PHYSICAL_ADAPTER_PNP_KEY structure holds information to query the physical adapter PNP key.
Syntax
typedef struct _D3DKMT_QUERY_PHYSICAL_ADAPTER_PNP_KEY {
UINT PhysicalAdapterIndex;
D3DKMT_PNP_KEY_TYPE PnPKeyType;
WCHAR *pDest;
UINT *pCchDest;
} D3DKMT_QUERY_PHYSICAL_ADAPTER_PNP_KEY;
Members
PhysicalAdapterIndex
The physical adapter index in the LDA (linked display adapter) chain.
PnPKeyType
A D3DKMT_PNP_KEY_TYPE enumeration value that specifies the type of the PNP key being queried.
pDest
Pointer to a buffer that receives the requested PnP key as a wide-character string.
pCchDest
Pointer to a variable that specifies the size of the pDest buffer, in characters. On input, it should contain the maximum number of characters that can be stored in the buffer. On output, it is updated to reflect the actual number of characters written to pDest, including the null terminator.
