ITLegacyAddressMediaControl::SetDevConfig method (tapi3if.h)

The SetDevConfig function allows the application to restore the configuration of a media stream device on a line device to a setup previously obtained using GetDevConfig.

HRESULT SetDevConfig(
  BSTR  pDeviceClass,
  DWORD dwSize,
  BYTE  *pDeviceConfig
);

Parameters

pDeviceClass

Pointer to BSTR containing TAPI device class for which configuration information is needed.

dwSize

Size of configuration array.

pDeviceConfig

Pointer to the array of bytes containing device configuration information obtained by a call to GetDevConfig.

This method is a COM wrapper for the lineSetDevConfig TAPI 2.1 function.

The GetID must be performed prior to calling this method.

The application must use SysAllocString to allocate memory for the pDeviceClass parameter and use SysFreeString to free the memory when the variable is no longer needed.
