8.44. Config

Used to access
configuration information. When Perl is built, the Configure script
obtains and saves this information in a hash,
%Config, in Config.pm itself.
Config checks to be sure it''s running with the same
Perl version as the one that created the hash.

The index into the hash is the shell variable name.
%Config is always exported; the following three
functions are exported on request.

>

config_sh

use Config(qw(config_sh));
print config_sh( );

archlibexp=''sun4-solaris''

config_vars (names)

Returns the name/value pairs for the requested configuration
variables. Prints the results to STDOUT.

use Config(qw(config_vars));
print config_vars(qw(osname ccflags));
