WlanSetInterface (Compact 7)

3/12/2014

This function sets user-configurable parameters for a specified interface.

Syntax

DWORD WINAPI WlanSetInterface(
  __in        HANDLE hClientHandle,
  __in        const GUID* pInterfaceGuid,
  __in        WLAN_INTF_OPCODE OpCode,
  __in        DWORD dwDataSize,
  __in        const PVOID pData,
  __reserved  PVOID pReserved
);

Parameters

  • hClientHandle
    Client session handle, obtained by a previous call to the WlanOpenHandle function.
  • pInterfaceGuid
    The GUID of the interface to be configured.
  • OpCode
    A WLAN_INTF_OPCODE value that specifies the parameter to be set. The following table lists the valid constants alongside the data type of the parameter in pData:

    WLAN_INTF_OPCODE Value pDatadata type Description

    wlan_intf_opcode_autoconf_enabled

    BOOL

    Enables or disables automatic configuration for the indicated interface.

    wlan_intf_opcode_background_scan_enabled

    BOOL

    Enables or disables background scan for the indicated interface.

    wlan_intf_opcode_radio_state

    WLAN_PHY_RADIO_STATE

    Sets the radio state.

    wlan_intf_opcode_bss_type

    DOT11_BSS_TYPE

    Sets the BSS type.

    wlan_intf_opcode_media_streaming_mode

    BOOL

    Sets media streaming mode for the driver.

    wlan_intf_opcode_current_operation_mode

    ULONG

    Sets the current operation mode for the interface.

  • dwDataSize
    The size of the pData parameter, in bytes. If dwDataSize is larger than the actual amount of memory allocated to pData, an access violation will occur in the calling program.
  • pData
    The value to be set as specified by the OpCode parameter. The type of data pointed to by pData must be appropriate for the specified OpCode. Use the previous table to determine the type of data to use.

    Note

    If OpCode is set to wlan_intf_opcode_autoconf_enabled, wlan_intf_opcode_background_scan_enabled, or wlan_intf_opcode_media_streaming_mode, pData can point to an integer value. If pData points to 0, the value is converted to FALSE. If pData points to a nonzero integer, the value is converted to TRUE.

  • pReserved
    Reserved; set to NULL.

Return Values

Value Description

ERROR_SUCCESS

The function succeeds.

ERROR_ACCESS_DENIED

The caller does not have sufficient permissions to perform the requested operation.

ERROR_GEN_FAILURE

The parameter specified by OpCode is not supported by the driver or network adapter.

ERROR_INVALID_HANDLE

The handle hClientHandle was not found in the handle table.

ERROR_INVALID_PARAMETER

One of the following conditions occurred:

  • hClientHandle is NULL or invalid.
  • pInterfaceGuid is NULL.
  • pData is NULL.
  • pReserved is not NULL.
  • OpCode is set to wlan_intf_opcode_current_operation_mode and pData points to a value other than DOT11_OPERATION_MODE_EXTENSIBLE_STATION or DOT11_OPERATION_MODE_NETWORK_MONITOR.

RPC_STATUS

Can be any remote procedure call (RPC) error code. The RPC call may be unsuccessful due to Wlan RPC server issues, such as when the RPC server is not started. Refer to RPC for more information.

Remarks

When OpCode is set to wlan_intf_opcode_current_operation_mode, WlanSetInterface sets the current operation mode of the wireless interface. Two operation modes are supported: DOT11_OPERATION_MODE_EXTENSIBLE_STATION and DOT11_OPERATION_MODE_NETWORK_MONITOR. The operation mode constants are defined in the header file Windot11.h. If pData does not point to one of these values when OpCode is set to wlan_intf_opcode_current_operation_mode, WlanSetInterface will fail with an error.
