archive_read_next_header, archive_read_next_header2 – functions for reading streaming archives

LIBRARY SYNOPSIS DESCRIPTION RETURN VALUES ERRORS SEE ALSO

Streaming Archive Library (libarchive, -larchive)

#include <archive.h>

int
archive_read_next_header(struct archive *, struct archive_entry **);

int
archive_read_next_header2(struct archive *, struct archive_entry *);

archive_read_next_header()	Read the header for the next entry and return a pointer to a struct archive_entry. This is a convenience wrapper around archive_read_next_header2() that reuses an internal struct archive_entry object for each request.
archive_read_next_header2()	Read the header for the next entry and populate the provided struct archive_entry.

These functions return ARCHIVE_OK (the operation succeeded), ARCHIVE_WARN (the operation succeeded but a non-critical error was encountered), ARCHIVE_EOF (end-of-archive was encountered), ARCHIVE_RETRY (the operation failed but can be retried), and ARCHIVE_FATAL (there was a fatal error; the archive should be closed immediately).

Detailed error codes and textual descriptions are available from the archive_errno() and archive_error_string() functions.
