archive_read_next_header, archive_read_next_header2 -- functions for reading streaming archives
LIBRARY
Streaming Archive Library (libarchive, -larchive)
SYNOPSIS
#include <archive.h>
int
archive_read_next_header(struct archive *, struct archive_entry **);
int
archive_read_next_header2(struct archive *, struct archive_entry *);
DESCRIPTION
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.
RETURN VALUES
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).
ERRORS
Detailed error codes and textual descriptions are available from the archive_errno() and archive_error_string() functions.

The program above exits without freeing the memory.
In this case will the 1 gb of heap memory be returned... (9 Replies)
