Syntax

DWORD WINAPI WlanGetNetworkBssList(
  __in        HANDLE hClientHandle,
  __in        const GUID* pInterfaceGuid,
  __opt       const  PDOT11_SSID pDot11Ssid,
  __in        DOT11_BSS_TYPE dot11BssType,
  __in        BOOL bSecurityEnabled,
  __reserved  PVOID pReserved,
  __out       PWLAN_BSS_LIST* ppWlanBssList
);

  • hClientHandle
    The client's session handle, obtained by a previous call to the WlanOpenHandle function.
  • pInterfaceGuid
    The GUID of the interface to be queried
  • pDot11Ssid
    Pointer to a DOT11_SSID structure that specifies the SSID of the network from which the BSS list is requested. This parameter is optional. When set to NULL, the returned list contains all available BSSs.
  • dot11BssType
    A DOT11_BSS_TYPE value that indicates the BSS type of the network. This parameter is valid only when pDot11Ssid is not set to NULL.
