NAME

       th_get_pathname,   th_get_uid,	th_get_gid,   th_get_mode,   th_get_crc,   th_get_size,  th_get_mtime,	th_get_devmajor,  th_get_devminor,
       th_get_linkname - extract individual fields of a tar header

       TH_ISREG, TH_ISLNK, TH_ISSYM, TH_ISCHR, TH_ISBLK, TH_ISDIR, TH_ISFIFO - determine what kind of file a tar header refers to

       TH_ISLONGNAME, TH_ISLONGLINK - determine whether the GNU extensions are in use

SYNOPSIS

       #include <libtar.h>

       char *th_get_linkname(TAR *t);

       char *th_get_pathname(TAR *t);

       mode_t th_get_mode(TAR *t);

       int TH_ISLONGLINK(TAR *t);

VERSION

       This man page documents version 1.2 of libtar.

DESCRIPTION

       The th_get_*() functions extract individual fields from the current tar header associated with the TAR handle t.

       The TH_IS*() macros are used to evaluate what kind of file is pointed to by the current tar header associated with the TAR handle t.

       The TH_ISLONGNAME() and TH_ISLONGLINK() macros evaluate whether or not the GNU extensions are used by the  current  tar	header	associated
       with the TAR handle t.  This is only relevant if the TAR_GNU option was used when tar_open() was called.
