NAME

       archive_read_extract,  archive_read_extract2,  archive_read_extract_set_progress_callback — functions for
       reading streaming archives

LIBRARY

       Streaming Archive Library (libarchive, -larchive)

SYNOPSIS

       #include <archive.h>

       int
       archive_read_extract(struct archive *, struct archive_entry *, int flags);

       int
       archive_read_extract2(struct archive *src, struct archive_entry *, struct archive *dest);

       void
       archive_read_extract_set_progress_callback(struct archive *, void (*func)(void *), void *user_data);

DESCRIPTION

       archive_read_extract(), archive_read_extract_set_skip_file()
               A convenience function that wraps the corresponding archive_write_disk(3) interfaces.  The  first
               call  to  archive_read_extract()  creates  a  restore  object using archive_write_disk_new(3) and
               archive_write_disk_set_standard_lookup(3),          then          transparently           invokes
               archive_write_disk_set_options(3),     archive_write_header(3),     archive_write_data(3),    and
               archive_write_finish_entry(3) to create the entry on disk and  copy  data  into  it.   The  flags
               argument is passed unmodified to archive_write_disk_set_options(3).
       archive_read_extract2()
               This  is  another  version  of archive_read_extract() that allows you to provide your own restore
               object.  In particular,  this  allows  you  to  override  the  standard  lookup  functions  using
               archive_write_disk_set_group_lookup(3),  and  archive_write_disk_set_user_lookup(3).   Note  that
               archive_read_extract2()   does   not    accept    a    flags    argument;    you    should    use
               archive_write_disk_set_options() to set the restore options yourself.
       archive_read_extract_set_progress_callback()
               Sets  a pointer to a user-defined callback that can be used for updating progress displays during
               extraction.  The progress function will be invoked during the extraction of large regular  files.
               The  progress  function  will  be invoked with the pointer provided to this call.  Generally, the
               data pointed to should include a reference to the archive object and the archive_entry object  so
               that various statistics can be retrieved for the progress display.

RETURN VALUES

       Most  functions return zero on success, non-zero on error.  The possible return codes include: 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.
