config_vars#

Print selected configuration entries to STDOUT.

Synopsis#

use Config;
Config::config_vars(qw(archname osname ivsize));

What you get back#

Nothing. Each named key is written to STDOUT on its own line as key='value';. Unknown keys render with an empty value.

Examples#

use Config;
Config::config_vars('archname');           # archname='x86_64-linux';
Config::config_vars('archname', 'osname'); # two lines

Edge cases#

  • Empty key names are skipped silently.

  • Output goes straight to the OS STDOUT; redirecting with local *STDOUT in Perl does not affect it.

Differences from upstream#

Fully compatible with upstream.
