tar_extract_file, tar_extract_regfile, tar_extract_hardlink, tar_extract_symlink, tar_extract_chardev,

       The  tar_extract_file()  function  acts as a front-end to the other tar_extract_*() functions.  It checks
       the current tar header associated with the TAR handle t (which  must  be  initialized  first  by  calling
       th_read())  to  determine  what  kind  of  file  the  header  refers  to.   It then calls the appropriate
       tar_extract_*() function to extract that kind of file.

       The tar_skip_regfile() function skips over the file content blocks and positions the file pointer at  the
       expected location of the next tar header block.

       The  tar_set_file_perms() function sets the attributes of the extracted file to match the encoded values.
       This includes the file's modification time, mode, owner,  and  group.   This  function  is  automatically
       called  by  tar_extract_file(),  but applications which call the other tar_extract_*() functions directly
       will need to call tar_set_file_perms() manually if this behavior is desired.

       The tar_extract_file() function will fail if:

       EEXIST If the O_NOOVERWRITE flag is set and the file already exists.

       The tar_extract_*() functions will fail if:

       EINVAL An entry could not be added to the internal file hash.

       EINVAL Less than T_BLOCKSIZE bytes were read from the tar archive.

       EINVAL The  current  file  header associated with t refers to a kind of file other than the one which the
              called function knows about.

       They may also fail if any of the following functions fail: mkdir(), write(), link(), symlink(),  mknod(),
       mkfifo(), utime(), chown(), lchown(), chmod(), or lstat().

       tar_extract_blockdev, tar_extract_dir, tar_extract_fifo, tar_skip_regfile, tar_set_file_perms  -  extract
       files from a tar archive

       On successful completion, the functions documented here will return 0.  On failure, they will  return  -1
       and set errno to an appropriate value.

       The tar_extract_dir() function will return 1 if the directory already exists.
