SHCreateFileExtractIconW function (shlobj_core.h)

[SHCreateFileExtractIcon is available for use in the operating systems specified in the Requirements section. It may be altered or unavailable in subsequent versions.]

Creates a default IExtractIcon handler for a file system object. Namespace extensions that display file system objects typically use this function. The extension and file attributes derive all that is needed for a simple icon extractor.

Syntax

SHSTDAPI SHCreateFileExtractIconW(
  [in] LPCWSTR pszFile,
  [in] DWORD   dwFileAttributes,
  [in] REFIID  riid,
       void    **ppv
);

Parameters

[in] pszFile

Type: LPCTSTR

A pointer to a null-terminated string that specifies the file system object. The buffer must not exceed MAX_PATH characters in length.

[in] dwFileAttributes

A combination of one or more file attribute flags (FILE_ATTRIBUTE_* values as defined in Winnt.h) that specify the type of object.

[in] riid

Type: REFIID

Reference to the desired interface ID of the icon extractor interface to create. This must be either IID_IExtractIconA or IID_IExtractIconW.

ppv

Type: void**

When this function returns, contains the interface pointer requested in riid. This is typically IExtractIcon.

Return value

Type: HRESULT

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