IWICBitmapCodecInfo::GetDeviceManufacturer method (wincodec.h)

Retrieves the name of the device manufacture associated with the codec.

Syntax

HRESULT GetDeviceManufacturer(
  [in]      UINT  cchDeviceManufacturer,
  [in, out] WCHAR *wzDeviceManufacturer,
  [out]     UINT  *pcchActual
);

Parameters

[in] cchDeviceManufacturer

Type: UINT

The size of the device manufacture's name. Use 0 on first call to determine needed buffer size.

[in, out] wzDeviceManufacturer

Type: WCHAR*

Receives the device manufacture's name. Use NULL on first call to determine needed buffer size.

[out] pcchActual

Type: UINT*

The actual buffer size needed to retrieve the device manufacture's name.

Return value

Type: HRESULT

If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

Remarks

The usage pattern for this method is a two call process. The first call retrieves the buffer size needed to retrieve the full color management version number by calling it with cchDeviceManufacturer set to 0 and wzDeviceManufacturer set to NULL. This call sets pcchActual to the buffer size needed. Once the needed buffer size is determined, a second GetDeviceManufacturer call with cchDeviceManufacturer set to the buffer size and wzDeviceManufacturer set to a buffer of the appropriate size will retrieve the pixel formats.
