Retrieves the attributes of one or more file objects or subfolders.
Returns NOERROR if successful, or an OLE-defined error value otherwise.
cidl - Number of file objects from which to retrieve attributes.
apidl - Address of an array of pointers to ITEMIDLIST structures, each
of which uniquely identifies a file object relative to the parent
folder. Each ITEMIDLIST structure must contain exactly one
SHITEMID structure followed by a terminating zero.
rgfInOut - Address of a single ULONG value that, on entry, contains the
attributes that the caller is requesting. On exit, this value
contains the requested attributes that are common to all of the
specified objects. Note that this is the address of a single
ULONG value, not an array of ULONG values. The lists below
describe the possible flags for this parameter.
For list of flags refer to the documentation. I list here only ones we are
particular interested in:
SFGAO_HASSUBFOLDER - The specified folders have subfolders (and are, therefore,
expandable in the left pane of Windows Explorer).
SFGAO_FILESYSTEM - The specified folders or file objects are part of the
file system (that is, they are files, directories, or
root directories).
SFGAO_FILESYSANCESTOR - The specified folders contain one or more file system
folders.
SFGAO_FOLDER - The specified items are folders.
SFGAO_REMOVABLE - The specified file objects or folders are on removable
media.
SFGAO_VALIDATE - Validate cached information. The shell will validate that
the objects specified in a pidl still exist and will not
used cached information when retrieving the attributes.
If one or more of the items specified in a pidl no longer
exist, this method will return an error code. If cidl is
zero, the shell will discard all cached information for
the shell folder. This is similar to doing a refresh of
the folder.
