Determine if a stream is full buffered

I know the __flbf function can tell me if a stream is line buffered or not in Linux, but how to determine if a stream is full buffered or not?

Can't you use a combination of __flbf and __fbufsize to see if the file is unbuffered, line buffered or block buffered?

Like

if (__flbf(some_file))
    printf("File is line buffered\n");
else if (__fbufsize(some_file) == 0)
    printf("File is unbuffered\n");
else
    printf("File is block (aka fully) buffered\n");
