[The feature associated with this page, Windows Media Format 11 SDK, is a legacy feature. It has been superseded by Source Reader and Sink Writer. Source Reader and Sink Writer have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use Source Reader and Sink Writer instead of Windows Media Format 11 SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The SetClientInfo method sets client-side information used for logging. Use this method to specify information about the client that the reader object sends to the server for logging. If the application does not call this method, the reader object uses default values.

Syntax

HRESULT SetClientInfo(
  [in] WM_READER_CLIENTINFO *pClientInfo
);

Parameters

[in] pClientInfo

Pointer to a WM_READER_CLIENTINFO structure allocated by the caller, which contains information about the client.

Return value

The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.

Return code	Description
S_OK	The method succeeded.
E_INVALIDARG	Invalid argument. The cbSize member must be set, and the string values must not exceed 1024 characters.

Remarks

Initialize the WM_READER_CLIENTINFO structure before calling this method. Always set the cbSize member equal to the size of the structure, and set any unused fields to zero.


WM_READER_CLIENTINFO info;
ZeroMemory(&info, sizeof(WM_READER_CLIENTINFO));
info.cbSize = sizeof(WM_READER_CLIENTINFO);

// Set other fields (not shown).

hr = pReaderAdvanced->SetClientInfo( &info );
