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.
