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 |
config_sh
Returns all Perl configuration information.
use Config(qw(config_sh)); print config_sh( );
returns:
archlibexp='sun4-solaris' cc='cc' ccflags='-I/usr/local/include/sfio -I/usr/local/include' ...
| config_vars |
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));
returns:
osname='solaris' ccflags='-I/usr/local/include/sfio -I/usr/local/include'
