NAME
xsubpp - compiler to convert Perl XS code into C code
SYNOPSIS
xsubpp [-v] [-C++] [-except] [-s pattern] [-prototypes] [-noversioncheck] [-nolinenumbers] [-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.
- -nolinenumbers
-
Prevents the inclusion of `#line' directives in the output.
ENVIRONMENT
No environment variables are used.
