DESCRIPTION
       The  th_read()  function  reads	the next block from the tar archive associated with the TAR handle t.  It then sets the current tar header

       The th_write() function writes the contents of the current tar header associated with t to the tar archive associated with t.

RETURN VALUE
       On successful completion, th_read() and th_write() will return 0.  On failure, they will return -1 and set errno to an appropriate value.

       On EOF, th_read() will return 1.

ERRORS
       th_read() and th_write() will fail if:

       EINVAL Less than T_BLOCKSIZE blocks were read or written.
