=item xsinit()
-Generate C/C++ code for the XS intializer function.
+Generate C/C++ code for the XS initializer function.
When invoked as C<`perl -MExtUtils::Embed -e xsinit --`>
the following options are recognized:
-B<-o> <output filename> (Defaults to B<perlxsi.c>)
+B<-o> E<lt>output filenameE<gt> (Defaults to B<perlxsi.c>)

=item Examples

perl -MExtUtils::Embed -e xsinit -- -o xsinit.c Socket
This will generate code with an B<xs_init> function that glues the perl B<Socket::bootstrap> function
-to the C B<boot_Socket> function and writes it to a file named "xsinit.c".

with the current Perl.
-B<-I> <path1:path2>
+B<-I> E<lt>path1:path2E<gt>

In addition, when ModuleName.a is found, additional linker arguments
are picked up from the B<extralibs.ld> file in the same directory.
perl -MExtUtils::Embed -e ldopts -- -std Socket
-
+
This will do the same as the above example, along with printing additional arguments for linking with the B<Socket> extension.
For including perl header files this function simply prints:
- -I $Config{archlib}/CORE
+ -I$Config{archlibexp}/CORE
So, rather than having to say:
- perl -MConfig -e 'print "-I $Config{archlib}/CORE"'
+ perl -MConfig -e 'print "-I$Config{archlibexp}/CORE"'
Just say:
This function returns a string of calls to B<newXS()> that glue the module B<bootstrap>
function to B<boot_ModuleName> for each @modules.
-B<xsinit()> uses the xsi_* functions to generate most of it's code.
+B<xsinit()> uses the xsi_* functions to generate most of its code.
