GetAdapterInfo Parameter Block 8

You can use vendor-speciﬁc call #6 to get information about an adapter that interfaces to

a speciﬁed socket.

// vendor-specific call #6

The parameter block associated with this function is as follows:

typedef struct VendorSpecificPB VendorSpecificPB;

struct VendorSpecificPB

{

UInt32 clientHandle; // → clientHandle returned by RegisterClient

UInt16 vsCode; // → vsCode = 6

UInt16 socket; // → socket number

UInt32 dataLen; // → length of GetAdapterInfoPB plus space for

// voltages

UInt8 *vsDataPtr; // → GetAdapterInfoPB * (supplied by client)

};

typedef struct GetAdapterInfoPB GetAdapterInfoPB;

struct GetAdapterInfoPB

{

UInt32 attributes; // ← capabilities of socket's adapter

UInt16 revision; // ← revision ID of adapter

UInt16 reserved; //

UInt16 numVoltEntries; // ← number of valid voltage values

UInt8 *voltages; // <-> array of BCD voltage values

};

// 'attributes' field values

enum

{

csLevelModeInterrupts = 0x00000001,

csPulseModeInterrupts = 0x00000002,

csProgrammableWindowAddr = 0x00000004,

csProgrammableWindowSize = 0x00000008,

csSocketSleepPower = 0x00000010,
