The RtlIsPartialPlaceholderFileHandle routine determines if a file is a known type of placeholder, based on a file handle.
NTSYSAPI NTSTATUS RtlIsPartialPlaceholderFileHandle( HANDLE FileHandle, PBOOLEAN IsPartialPlaceholder );
FileHandle is a handle to the placeholder file whose partial state is to be queried. The file handle must have at least FILE_READ_ATTRIBUTES access.
IsPartialPlaceholder is a pointer to a boolean which is TRUE if the file or directory is a placeholder. It returns FALSE if either the file or directory is not a placeholder or is a full placeholder; undefined on failure.
Returns STATUS_SUCCESS if IsPartialPlaceholder is valid and not undefined.
