NAME ExtUtils::ParseXS - converts Perl XS code into C code SYNOPSIS use ExtUtils::ParseXS qw(process_file); process_file( filename => 'foo.xs' ); process_file( filename => 'foo.xs', output => 'bar.c', 'C++' => 1, typemap => 'path/to/typemap', hiertype => 1, except => 1, prototypes => 1, versioncheck => 1, linenumbers => 1, optimize => 1, prototypes => 1, ); =head1 DESCRIPTION "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. ../../../typemap:../../typemap:../typemap:typemap EXPORT None by default. "process_file()" may be exported upon request. FUNCTIONS process_xs() This function processes an XS file and sends output to a C file. Named parameters control how the processing is done. The following parameters are accepted: C++ Adds "extern "C"" to the C code. Default is false. hiertype Retains "::" in type names so that C++ hierachical types can be mapped. Default is false. except Adds exception handling stubs to the C code. Default is false. typemap 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 precedence. prototypes Generates prototype code for all xsubs. Default is false. versioncheck 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. linenumbers Adds "#line" directives to the C output so error messages will look like they came from the original XS file. Default is true. optimize Enables certain optimizations. The only optimization that is currently affected is the use of *target*s by the output C code (see the perlguts manpage). 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. inout Enable recognition of "IN", "OUT_LIST" and "INOUT_LIST" declarations. Default is true. argtypes Enable recognition of ANSI-like descriptions of function signature. Default is true. s I have no clue what this does. Strips function prefixes? errors() This function returns the number of [a certain kind of] errors encountered during processing of the XS file.
