Config::Extensions(3pm)                         Perl Programmers Reference Guide                         Config::Extensions(3pm)



NAME
       Config::Extensions - hash lookup of which core extensions were built.

SYNOPSIS
           use Config::Extensions '%Extensions';
           if ($Extensions{PerlIO::via}) {
               # This perl has PerlIO::via built
           }

DESCRIPTION
       The Config::Extensions module provides a hash %Extensions containing all the core extensions that were enabled for this
       perl. The hash is keyed by extension name, with each entry having one of 3 possible values:

       dynamic
           The extension is dynamically linked

       nonxs
           The extension is pure perl, so doesn't need linking to the perl executable

       static
           The extension is statically linked to the perl binary

       As all values evaluate to true, a simple "if" test is good enough to determine whether an extension is present.

       All the data uses to generate the %Extensions hash is already present in the "Config" module, but not in such a
       convenient format to quickly reference.
