=head1 NAME
xsubpp - compiler to convert Perl XS code into C code
=head1 SYNOPSIS
B<xsubpp> [B<-v>] [B<-except>] [B<-s pattern>] [B<-prototypes>] [B<-noversioncheck>] [B<-nolinenumbers>] [B<-nooptimize>] [B<-typemap typemap>] [B<-output filename>]... file.xs
=head1 DESCRIPTION
This compiler is typically run by the makefiles created by L<ExtUtils::MakeMaker>
or by L<Module::Build> or other Perl module build tools.
I<xsubpp> will compile XS code into C code by embedding the constructs
necessary to let C functions manipulate Perl values and creates the glue
necessary to let Perl access those functions. The compiler uses typemaps to
determine how to map C function parameters and variables to Perl values.
The compiler will search for typemap files called I<typemap>. It will use
the following search path to find default typemaps, with the rightmost
typemap taking precedence.
../../../typemap:../../typemap:../typemap:typemap
It will also use a default typemap installed as C<ExtUtils::typemap>.
=head1 OPTIONS
Note that the C<XSOPT> MakeMaker option may be used to add these options to
any makefiles generated by MakeMaker.
=over 5
=item B<-hiertype>
Retains '::' in type names so that C++ hierarchical types can be mapped.
=item B<-except>
Adds exception handling stubs to the C code.
=item B<-typemap typemap>
Indicates that a user-supplied typemap should take precedence over the
default typemaps. This option may be used multiple times, with the last
typemap having the highest precedence.
=item B<-output filename>
Specifies the name of the output file to generate. If no file is
specified, output will be written to standard output.
=item B<-v>
Prints the I<xsubpp> version number to standard output, then exits.
=item B<-prototypes>
By default I<xsubpp> will not automatically generate prototype code for
all xsubs. This flag will enable prototypes.
=item B<-noversioncheck>
Disables the run time test that determines if the object file (derived
from the C<.xs> file) and the C<.pm> files have the same version
number.
=item B<-nolinenumbers>
Prevents the inclusion of '#line' directives in the output.
=item B<-nooptimize>
Disables certain optimizations. The only optimization that is currently
affected is the use of I<target>s by the output C code (see L<perlguts>).
This may significantly slow down the generated code, but this is the way
B<xsubpp> of 5.005 and earlier operated.
=item B<-noinout>
Disable recognition of C<IN>, C<OUT_LIST> and C<INOUT_LIST> declarations.
=item B<-noargtypes>
Disable recognition of ANSI-like descriptions of function signature.
=item B<-C++>
Currently doesn't do anything at all. This flag has been a no-op for
many versions of perl, at least as far back as perl5.003_07. It's
allowed here for backwards compatibility.
=item B<-s=...> or B<-strip=...>
I<This option is obscure and discouraged.>
If specified, the given string will be stripped off from the beginning
of the C function name in the generated XS functions (if it starts with that prefix).
This only applies to XSUBs without C<CODE> or C<PPCODE> blocks.
For example, the XS:
void foo_bar(int i);
when C<xsubpp> is invoked with C<-s foo_> will install a C<foo_bar>
function in Perl, but really call C<bar(i)> in C. Most of the time,
this is the opposite of what you want and failure modes are somewhat
obscure, so please avoid this option where possible.
