Subject: how to find size of special file

Stupid question du jour:

How do you find out a size of a raw or cooked disk partition?  Neither
the obvious

    int fd ;
    struct stat sb ;
    fd = open(filename, ...) ;
    stat(fd, &sb) ;
    size = sb.st_size ;

nor the less obvious

    int fd ;
    struct stat sb ;
    fd = open(filename, ...) ;
    size = lseek(fd, 0, SEEK_END) ;

work on special files, even if they are disk partitions.  (They both
work on regular files....)
