    Since you have not given any information on where you see this I will assume you are running GNU lsof with no arguments and you see 0t0 in the SIZE/OFF column. This, by default, shows the size of the file in question.

    However, for "special" files, it ...

    SIZE, SIZE/OFF, or OFFSET
    is the size of the file or the file offset in bytes. A value is displayed in
    this column only if it is available. Lsof displays whatever value - size or
    offset - is appropriate for the type of the file and the version of lsof.

    How do I know if a file is 0t0?
    For all I know you have a file called 0t0, we have no way of knowing what you're talking about if you don't show some sample output. Since you have not given any information on where you see this I will assume you are running GNU lsof with no arguments and you see 0t0 in the SIZE/OFF column. This, by default, shows the size of the file in question.
