xsubpp

NAME

       xsubpp - compiler to convert Perl XS code into C code

SYNOPSIS

       xsubpp [-v] [-C++] [-except] [-s pattern] [-prototypes]
       [-noversioncheck] [-typemap typemap]... file.xs

DESCRIPTION

       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

OPTIONS

       -C++ Adds ``extern "C"'' to the C code.

       -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.

       -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.

ENVIRONMENT

       No environment variables are used.
