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 or download 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.

    7 perlfreebsd - Perl version 5 on FreeBSD systems
    8 
    9 =head1 DESCRIPTION
   10 
   11 This document describes various features of FreeBSD that will affect how Perl
   12 version 5 (hereafter just Perl) is compiled and/or runs.
   13 
   14 =head2 FreeBSD core dumps from readdir_r with ithreads
   15 
   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 a bug in FreeBSD's
   18 C<readdir_r> function in versions 4.5 and earlier that can cause a SEGV when
   19 reading large directories. A patch for FreeBSD libc is available
   20 (see L<http://www.freebsd.org/cgi/query-pr.cgi?pr=misc/30631> )
   21 which has been integrated into FreeBSD 4.6.
   22 
   23 =head2 C<$^X> doesn't always contain a full path in FreeBSD
   24 
   25 perl sets C<$^X> where possible to a full path by asking the operating
   26 system. On FreeBSD the full path of the perl interpreter is found by using
   27 C<sysctl> with C<KERN_PROC_PATHNAME> if that is supported, else by reading
   28 the symlink F</proc/curproc/file>. FreeBSD 7 and earlier has a bug where
   29 either approach sometimes returns an incorrect value
   30 (see L<http://www.freebsd.org/cgi/query-pr.cgi?pr=35703> ).
   31 In these cases perl will fall back to the old behaviour of using C's
   32 C<argv[0]> value for C<$^X>.
