Question

I’m translating a C++ Windows API to a delphi *.pas file.

I have this C Struct returned by a function

typedef struct _WLAN_HOSTED_NETWORK_STATUS {
  WLAN_HOSTED_NETWORK_STATE      HostedNetworkState;
  GUID                           IPDeviceID;
  DOT11_MAC_ADDRESS              wlanHostedNetworkBSSID;
  DOT11_PHY_TYPE                 dot11PhyType;
  ULONG                          ulChannelFrequency;
  DWORD                          dwNumberOfPeers;
  WLAN_HOSTED_NETWORK_PEER_STATE PeerList[1];
} WLAN_HOSTED_NETWORK_STATUS, *PWLAN_HOSTED_NETWORK_STATUS;

I translated to this:

type
_WLAN_HOSTED_NETWORK_STATUS = record 
  HostedNetworkState : WLAN_HOSTED_NETWORK_STATE;
  IPDeviceID : GUID;
  wlanHostedNetworkBSSID : DOT11_MAC_ADDRESS;
  dot11PhyType : DOT11_PHY_TYPE;
  ulChannelFrequency : ULONG;
  dwNumberOfPeers : DWORD;
  PeerList : Array [0..1] of WLAN_HOSTED_NETWORK_PEER_STATE;
end;
WLAN_HOSTED_NETWORK_STATUS = _WLAN_HOSTED_NETWORK_STATUS;
PWLAN_HOSTED_NETWORK_STATUS = _WLAN_HOSTED_NETWORK_STATUS;

but I not found on MSDN reference what is this GUID type of IPDeviceID
it is a primitive type? how do I hold this value?

The Delphi equivalent is TGUID.

The Delphi documentation contains some examples of how to use this type and its associated helper function.
