As a special service "Fossies" has tried to format the requested text file into HTML format (style: standard
) with prefixed line numbers.
Alternatively you can here view
the uninterpreted source code file.
1 If you read this file _as_is_, just ignore the funny characters you
2 see. It is written in the POD format (see pod/perlpod.pod) which is
3 specifically designed to be readable as is.
5 =head1 NAME
7 perlopenbsd - Perl version 5 on OpenBSD systems
9 =head1 DESCRIPTION
11 This document describes various features of OpenBSD that will affect how Perl
12 version 5 (hereafter just Perl) is compiled and/or runs.
14 =head2 OpenBSD core dumps from getprotobyname_r and getservbyname_r with ithreads
16 When Perl is configured to use ithreads, it will use re-entrant library calls
17 in preference to non-re-entrant versions. There is an incompatibility in
18 OpenBSD's C<getprotobyname_r> and C<getservbyname_r> function in versions 3.7
19 and later that will cause a SEGV when called without doing a C<bzero> on
20 their return structs prior to calling these functions. Current Perl's
21 should handle this problem correctly. Older threaded Perls (5.8.6 or earlier)
22 will run into this problem. If you want to run a threaded Perl on OpenBSD
23 3.7 or higher, you will need to upgrade to at least Perl 5.8.7.
