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

10 if ($Extensions{PerlIO::via}) {
11 # This perl has PerlIO::via built

15 The Config::Extensions module provides a hash %Extensions containing
16 all the core extensions that were enabled for this perl. The hash is
17 keyed by extension name, with each entry having one of 3 possible
18 values:
19
20 dynamic
21 The extension is dynamically linked
22
23 nonxs
24 The extension is pure perl, so doesn't need linking to the perl
25 executable
26
27 static
28 The extension is statically linked to the perl binary
29
30 As all values evaluate to true, a simple "if" test is good enough to
31 determine whether an extension is present.
32
33 All the data uses to generate the %Extensions hash is already present
34 in the "Config" module, but not in such a convenient format to quickly
35 reference.
