th_read, th_write - read and write a file header block from a tar archive

       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 associated with t to the contents of the block read.

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

th_read() and th_write() will fail if:

       EINVAL Less than T_BLOCKSIZE blocks were read or written.

       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.
