Dot11ExtIhvPerformCapabilityMatch (Compact 7)

The operating system calls this function to request that the IHV Extensions DLL determine whether a detected basic service set (BSS) network matches the connectivity and security profile extensions defined by the IHV.

Syntax

DWORD WINAPI Dot11ExtIhvPerformCapabilityMatch(
    HANDLE hIhvExtAdapter,
    PDOT11EXT_IHV_PROFILE_PARAMS pIhvProfileParams,
    PDOT11EXT_IHV_CONNECTIVITY_PROFILE pIhvConnProfile,
    PDOT11EXT_IHV_SECURITY_PROFILE pIhvSecProfile,
    PDOT11_BSS_LIST pConnectableBssid,
    PDWORD pdwReasonCode
);

Parameters

  • hIhvExtAdapter
    [in] The handle that is used by the IHV Extensions DLL to reference the WLAN adapter. This handle value was specified through a previous call to the Dot11ExtIhvInitAdapter IHV Handler function.
  • pIhvProfileParams
    [in] A pointer to a DOT11EXT_IHV_PROFILE_PARAMS structure. This structure defines the attributes of the basic service set (BSS) network to which the profile extensions will be applied.
  • pConnectableBssid
    [in] A pointer to a DOT11_BSS_LIST structure. This contains one or more 802.11 Beacon or Probe Response frames received from a BSS network. This list is derived from the results of the last scan operation that was performed by the WLAN adapter.
  • pwdReasonCode
    [out] A pointer to a DWORD value, which provides additional information for the return value of the Dot11ExtIhvPerformCapabilityMatch function. The IHV Extensions DLL must set *pdwReasonCode to an L2_REASON_CODE_xxxx value, which are defined in L2cmn.h.

Return Value

If all entries in the list of 802.11 Beacon and Probe Response frames support the connectivity and security attributes defined in the profile fragments, the function returns ERROR_SUCCESS. Otherwise, it returns an error code defined in Winerror.h.

Remarks

After the WLAN adapter has completed a scan operation to detect the BSS networks within range, the operating system might call the Dot11ExtIhvPerformCapabilityMatch function to determine whether any of the detected BSS networks matches the connectivity or security profile extensions defined by the IHV.

When the Dot11ExtIhvPerformCapabilityMatch function is called, the IHV Extensions DLL must follow these guidelines:

  • If the IHV Extensions DLL finds at least one IEEE 802.11 Beacon or Probe Response frame that matches the profile fragments, it must set *pdwReasonCode to one of the following:
    • L2_REASON_CODE_SUCCESS
    • An IHV-defined value in the range from L2_REASON_CODE_IHV_BASE to (L2_REASON_CODE_IHV_BASE+ L2_REASON_CODE_GROUP_SIZE-1)
      In this situation, the Dot11ExtIhvPerformCapabilityMatch function must return ERROR_SUCCESS.
  • If the IHV Extensions DLL does not find an IEEE 802.11 Beacon or Probe Response frame that matches the profile fragments, it must not set *pdwReasonCode to L2_REASON_CODE_SUCCESS. Instead, the DLL must set *pdwReasonCode to one of the following:
    • An appropriate L2_REASON_CODE_xxxx error value
    • An IHV-defined value in the range from L2_REASON_CODE_IHV_BASE to (L2_REASON_CODE_IHV_BASE+ L2_REASON_CODE_GROUP_SIZE-1)
      In this situation, the Dot11ExtIhvPerformCapabilityMatch function must not return ERROR_SUCCESS.
