NAME
xsubpp - compiler to convert Perl XS code into C code
SYNOPSIS
xsubpp [-v] [-except] [-s pattern] [-prototypes]
[-noversioncheck] [-nolinenumbers] [-nooptimize] [-typemap
typemap] [-output filename]... file.xs
DESCRIPTION
This compiler is typically run by the makefiles created by
ExtUtils::MakeMaker.
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 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
"ExtUtils::typemap".
OPTIONS
Note that the "XSOPT" MakeMaker option may be used to add
these options to any makefiles generated by MakeMaker.
-hiertype
Retains '::' in type names so that C++ hierarchical
types can be mapped.
-except
Adds exception handling stubs to the C code.
-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.
-output filename
Specifies the name of the output file to generate. If
no file is specified, output will be written to
standard output.
-v Prints the xsubpp version number to standard output,
then exits.

-prototypes
By default xsubpp will not automatically generate
prototype code for all xsubs. This flag will enable
prototypes.
-noversioncheck
Disables the run time test that determines if the
object file (derived from the ".xs" file) and the ".pm"
files have the same version number.
-nolinenumbers
Prevents the inclusion of `#line' directives in the
output.
-nooptimize
Disables certain optimizations. The only optimization
that is currently affected is the use of targets by the
output C code (see perlguts). This may significantly
slow down the generated code, but this is the way
xsubpp of 5.005 and earlier operated.
-noinout
Disable recognition of "IN", "OUT_LIST" and
"INOUT_LIST" declarations.
-noargtypes
Disable recognition of ANSI-like descriptions of
function signature.
-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.
ENVIRONMENT
No environment variables are used.
