fn _tar_byte_at(buf: &i8, idx: i64) -> i64

Internal byte reader.

fn _tar_write_octal(out: &i8, pos: i64, val: i64, len: i64) -> i64

Internal: write octal string (zero-padded, len chars) at position. Writes right-to-left directly into output to avoid alloc_pages.

fn _tar_read_octal(buf: &i8, pos: i64, len: i64) -> i64

Internal: read octal number from buffer.

fn _tar_checksum(buf: &i8, pos: i64) -> i64

Internal: compute header checksum.

fn _tar_zero_block(buf: &i8, pos: i64) -> i64

Internal: zero-fill a 512-byte block.

fn tar_create(out: &i8) -> &i64

Create a write handle. out is the output buffer.

fn tar_add_file(h: &i64, name: &i8, nlen: i64, data: &i8, dlen: i64) -> i64

Add a file entry to the tar archive.

fn tar_finish(h: &i64) -> i64

Write two zero blocks to finish the archive. Returns total length.

fn tar_open(buf: &i8, len: i64) -> &i64

Open a tar archive for reading.

fn tar_next(h: &i64) -> i64

Advance to next entry. Returns 1 if entry found, 0 if end of archive.

fn tar_entry_name(h: &i64, out: &i8) -> i64

Copy current entry name to out. Returns length.

fn tar_entry_size(h: &i64) -> i64

Get size of current entry data.

fn tar_entry_data(h: &i64, out: &i8) -> i64

Copy current entry data to out. Returns length.
