NAME
tar_extract_file, tar_extract_regfile, tar_extract_hardlink, tar_extract_symlink, tar_extract_chardev, tar_extract_blockdev, tar_extract_dir, tar_extract_fifo, tar_skip_regfile, tar_set_file_perms - extract files from a tar archive
SYNOPSIS
#include <libtar.h> int tar_extract_file(TAR *t, char *realname); int tar_extract_regfile(TAR *t, char *realname); int tar_skip_regfile(TAR *t); int tar_extract_dir(TAR *t, char *realname); int tar_extract_hardlink(TAR *t, char *realname); int tar_extract_symlink(TAR *t, char *realname); int tar_extract_blockdev(TAR *t, char *realname); int tar_extract_chardev(TAR *t, char *realname); int tar_extract_fifo(TAR *t, char *realname); int tar_set_file_perms(TAR *t, char *realname);
VERSION
This man page documents version 1.2 of libtar.
DESCRIPTION
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 modifi- cation 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.
RETURN VALUES
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.
ERRORS
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().
