archive_util(3) BSD 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. SEE ALSO archive_read(3), archive_write(3), libarchive(3) HISTORY The libarchive library first appeared in FreeBSD 5.3. AUTHORS The libarchive library was written by Tim Kientzle <kientzle@acm.org>. BSD October 1, 2003 BSD
