SHCreateFileExtractIconA 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.
