| char *mime_type; | This is a char * identifying the type of the file, if valid_fields provides GNOME_VFS_FILE_INFO_FIELDS_MIME_TYPE. |
| guint refcount; | The reference count of this file info, which is one by default, and that can be increased using gnome_vfs_file_info_ref() and decreased using gnome_vfs_file_info_unref(). When it drops to zero, the file info is freed and its memory is invalid. Make sure to keep your own reference to a file info if you received it from GnomeVFS, i.e. if you didn't call gnome_vfs_file_info_new() yourself. |
