IDWriteRemoteFontFileLoader::CreateRemoteStreamFromKey method (dwrite_3.h)

  • Article

Creates a remote font file stream object that encapsulates an open file resource and can be used to download remote file data.

Syntax

HRESULT CreateRemoteStreamFromKey(
  [in]  void const                  *fontFileReferenceKey,
        UINT32                      fontFileReferenceKeySize,
  [out] IDWriteRemoteFontFileStream **fontFileStream
);

Parameters

[in] fontFileReferenceKey

Type: void

Font file reference key that uniquely identifies the font file resource within the scope of the font loader being used.

fontFileReferenceKeySize

Type: UINT32

Size of font file reference key in bytes.

[out] fontFileStream

Type: IDWriteRemoteFontFileStream**

Pointer to the newly created font file stream.

Return value

Type: HRESULT

This method returns an HRESULT success or error code.

Remarks

Unlike CreateStreamFromKey, this method can be used to create a stream for a remote file. If the file is remote, the client must call IDWriteRemoteFontFileStream::BeginDownload with an empty array of file fragments before the stream can be used to get the file size or access data.
