756 | ||
757 | use Config; | |
63f18be6 NC |
758 | if ($Config{usethreads}) { |
759 | print "has thread support\n" | |

771 | ||
772 | ||
773 | =head1 DESCRIPTION | |
774 | ||
775 | The Config module contains all the information that was available to | |
776 | the C<Configure> program at Perl build time (over 900 values). | |
777 | ||
778 | Shell variables from the F<config.sh> file (written by Configure) are | |
779 | stored in the readonly-variable C<%Config>, indexed by their names. | |
780 | ||
781 | Values stored in config.sh as 'undef' are returned as undefined | |
1fef88e7 | 782 | values. The perl C<exists> function can be used to check if a |
3c81428c | 783 | named variable exists. |
784 | ||
3acf89b2 MB |
785 | For a description of the variables, please have a look at the |
786 | Glossary file, as written in the Porting folder, or use the url: | |
787 | http://perl5.git.perl.org/perl.git/blob/HEAD:/Porting/Glossary | |
788 | ||
3c81428c | 789 | =over 4 |
790 | ||
791 | =item myconfig() | |
792 | ||
793 | Returns a textual summary of the major perl configuration values. | |
794 | See also C<-V> in L<perlrun/Switches>. | |
795 | ||
796 | =item config_sh() | |
797 | ||
798 | Returns the entire perl configuration information in the form of the | |
799 | original config.sh shell variable assignment script. | |
800 | ||
a48f8c77 MS |
801 | =item config_re($regex) |
802 | ||
803 | Like config_sh() but returns, as a list, only the config entries who's | |
804 | names match the $regex. | |
805 | ||
3c81428c | 806 | =item config_vars(@names) |
807 | ||
808 | Prints to STDOUT the values of the named configuration variable. Each is | |

818 | =head1 EXAMPLE | |
819 | ||
820 | Here's a more sophisticated example of using %Config: | |
821 | ||
822 | use Config; | |
743c51bc W |
823 | use strict; |
824 | ||
825 | my %sig_num; | |
826 | my @sig_name; | |
827 | unless($Config{sig_name} && $Config{sig_num}) { | |
828 | die "No sigs?"; | |
829 | } else { | |
830 | my @names = split ' ', $Config{sig_name}; | |
831 | @sig_num{@names} = split ' ', $Config{sig_num}; | |
832 | foreach (@names) { | |
833 | $sig_name[$sig_num{$_}] ||= $_; | |
834 | } | |
835 | } | |
3c81428c | 836 | |
743c51bc W |
837 | print "signal #17 = $sig_name[17]\n"; |
838 | if ($sig_num{ALRM}) { | |
839 | print "SIGALRM is $sig_num{ALRM}\n"; | |
3c81428c | 840 | } |
841 | ||
842 | =head1 WARNING | |
843 | ||
844 | Because this information is not stored within the perl executable | |
845 | itself it is possible (but unlikely) that the information does not | |
846 | relate to the actual perl binary which is being used to access it. | |
847 | ||
848 | The Config module is installed into the architecture and version | |
849 | specific library directory ($Config{installarchlib}) and it checks the | |
850 | perl version number when loaded. | |
851 | ||
435ec615 HM |
852 | The values stored in config.sh may be either single-quoted or |
853 | double-quoted. Double-quoted strings are handy for those cases where you | |
854 | need to include escape sequences in the strings. To avoid runtime variable | |
855 | interpolation, any C<$> and C<@> characters are replaced by C<\$> and | |
856 | C<\@>, respectively. This isn't foolproof, of course, so don't embed C<\$> | |
857 | or C<\@> in double-quoted strings unless you're willing to deal with the | |
858 | consequences. (The slashes will end up escaped and the C<$> or C<@> will | |
859 | trigger variable interpolation) | |

861 | =head1 GLOSSARY |
862 | ||
863 | Most C<Config> variables are determined by the C<Configure> script | |
864 | on platforms supported by it (which is most UNIX platforms). Some | |
865 | platforms have custom-made C<Config> variables, and may thus not have | |
866 | some of the variables described below, or may have extraneous variables | |
867 | specific to that particular port. See the port specific documentation | |
868 | in such cases. | |
