xsubpp - compiler to convert Perl XS code into C code
xsubpp [-v] [-C++] [-except] [-s pattern] [-prototypes]
[-noversioncheck] [-nolinenumbers] [-nooptimize] [-typemap
typemap] ... file.xs
This compiler is typically run by the makefiles created by
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
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.
Note that the "XSOPT" MakeMaker option may be used to add
these options to any makefiles generated by MakeMaker.
-C++ Adds ``extern "C"'' to the C code.
Retains '::' in type names so that C++ hierachical
types can be mapped.
Adds exception handling stubs to the C code.
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,
By default xsubpp will not automatically generate
prototype code for all xsubs. This flag will enable
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.
Prevents the inclusion of `#line' directives in the
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.
