IDWriteFontFileStream::GetFileSize method

Obtains the total size of a file.

Syntax

virtual HRESULT GetFileSize(
  [out] UINT64 * fileSize
) = 0;

Parameters

fileSize [out]

Type: UINT64*

When this method returns, contains the total size of the file.

Return value

Type: HRESULT

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

Remarks

Implementing GetFileSize() for asynchronously loaded font files may require downloading the complete file contents. Therefore, this method should be used only for operations that either require a complete font file to be loaded (for example, copying a font file) or that need to make decisions based on the value of the file size (for example, validation against a persisted file size).
