xsubpp - compiler to convert Perl
XS code into
C code
xsubpp [-v] [-C++] [-except] [-s pattern] [-prototypes] [-noversioncheck] [-nolinenumbers] [-typemap typemap] [-object_capi]... file.xs
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
- -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.
- -nolinenumbers
-
Prevents the inclusion of `#line' directives in the output.
- -object_capi
-
Compile code as
C in a
PERL_OBJECT environment.

DISCLAIMER
We are painfully aware that these documents may contain incorrect links and
misformatted HTML. Such bugs lie in the automatic translation process
that automatically created the hundreds and hundreds of separate documents that you find here. Please do
not report link or formatting bugs, because we cannot fix
per-document problems. The only bug reports that will help us are those
that supply working patches to the installhtml or pod2html
programs, or to the Pod::HTML module itself, for which I and the entire
Perl community will shower you with thanks and praises.
If rather than formatting bugs, you encounter substantive content errors in these documents, such as mistakes in
the explanations or code, please use the perlbug utility included
with the Perl distribution.
