archive_util(3)	       FreeBSD Library Functions Manual	       archive_util(3)

NAME
     archive_compression, archive_compression_name, archive_errno,
     archive_error_string, archive_format, archive_format_name,
     archive_set_error -- libarchive utility functions

SYNOPSIS
     #include <archive.h>

     int
     archive_compression(struct	archive	*);

     const char	*
     archive_compression_name(struct archive *);

     int
     archive_errno(struct archive *);

     const char	*
     archive_error_string(struct archive *);

     int
     archive_format(struct archive *);

     const char	*
     archive_format_name(struct	archive	*);

     int
     archive_set_error(struct archive *, int error_code, const char *fmt,
	 ...);

DESCRIPTION
     These functions provide access to various information about the struct
     archive object used in the	libarchive(3) library.
     archive_compression()
	     Returns a numeric code indicating the current compression.	 This
	     value is set by archive_read_open().
     archive_compression_name()
	     Returns a text description	of the current compression suitable
	     for display.
     archive_errno()
	     Returns a numeric error code (see errno(2)) indicating the	reason
	     for the most recent error return.
     archive_error_string()
	     Returns a textual error message suitable for display.  The	error
	     message here is usually more specific than	that obtained from
	     passing the result	of archive_errno() to strerror(3).
     archive_format()
	     Returns a numeric code indicating the format of the current ar-
	     chive entry.  This	value is set by	a successful call to
	     archive_read_next_header().  Note that it is common for this
	     value to change from entry	to entry.  For example,	a tar archive
	     might have	several	entries	that utilize GNU tar extensions	and
	     several entries that do not.  These entries will have different
	     format codes.
     archive_format_name()
	     A textual description of the format of the	current	entry.
     archive_set_error()
	     Sets the numeric error code and error description that will be
	     returned by archive_errno() and archive_error_string().  This
	     function is sometimes useful within I/O callbacks.
