       ExtUtils::ParseXS - converts Perl XS code into C code

         use ExtUtils::ParseXS;

         my $pxs = ExtUtils::ParseXS->new;
         $pxs->process_file( filename => 'foo.xs' );

         $pxs->process_file( filename => 'foo.xs',
                             output => 'bar.c',
                             'C++' => 1,
                             typemap => 'path/to/typemap',
                             hiertype => 1,
                             except => 1,
                             versioncheck => 1,
                             linenumbers => 1,
                             optimize => 1,

         process_file( filename => 'foo.xs' );

       "ExtUtils::ParseXS" 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.


       None by default.  "process_file()" and/or "report_error_count()" may be exported upon
       request. Using the functional interface is discouraged.

           Returns a new, empty XS parser/compiler object.

           This method processes an XS file and sends output to a C file.  The method may be
           called as a function (this is the legacy interface) and will then use a singleton as

           Named parameters control how the processing is done.  The following parameters are

           C++ Adds "extern "C"" to the C code.  Default is false.

               Retains "::" in type names so that C++ hierarchical types can be mapped.  Default
               is false.

               Adds exception handling stubs to the C code.  Default is false.

               Indicates that a user-supplied typemap should take precedence over the default
               typemaps.  A single typemap may be specified as a string, or multiple typemaps can
               be specified in an array reference, with the last typemap having the highest

               Generates prototype code for all xsubs.  Default is false.

               Makes sure at run time that the object file (derived from the ".xs" file) and the
               ".pm" files have the same version number.  Default is true.

               Adds "#line" directives to the C output so error messages will look like they came
               from the original XS file.  Default is true.

               Enables certain optimizations.  The only optimization that is currently affected
               is the use of targets by the output C code (see perlguts).  Not optimizing may
               significantly slow down the generated code, but this is the way xsubpp of 5.005
               and earlier operated.  Default is to optimize.

               Enable recognition of "IN", "OUT_LIST" and "INOUT_LIST" declarations.  Default is

               Enable recognition of ANSI-like descriptions of function signature.  Default is

           s   Maintainer note: I have no clue what this does.  Strips function prefixes?

           This method returns the number of [a certain kind of] errors encountered during
           processing of the XS file.

           The method may be called as a function (this is the legacy interface) and will then
           use a singleton as invocant.

       Based on xsubpp code, written by Larry Wall.
