# th\_get\_uid(3)

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

Part of [th\_get\_pathname(3)](/th_get_pathname/3.md).

## 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.
