+=head1 NAME
+
+h2xs - convert .h C header files to Perl extensions
+
+=head1 SYNOPSIS
+
+B<h2xs> [B<OPTIONS> ...] [headerfile ... [extra_libraries]]
+
+B<h2xs> B<-h>|B<-?>|B<--help>
+
+=head1 DESCRIPTION
+
+I<h2xs> builds a Perl extension from C header files. The extension
+will include functions which can be used to retrieve the value of any
+#define statement which was in the C header files.
+
+The I<module_name> will be used for the name of the extension. If
+module_name is not supplied then the name of the first header file
+will be used, with the first character capitalized.
+
+If the extension might need extra libraries, they should be included
+here. The extension Makefile.PL will take care of checking whether
+the libraries actually exist and how they should be loaded. The extra
+libraries should be specified in the form -lm -lposix, etc, just as on
+the cc command line. By default, the Makefile.PL will search through
+the library path determined by Configure. That path can be augmented
+by including arguments of the form B<-L/another/library/path> in the
+extra-libraries argument.
+
+In spite of its name, I<h2xs> may also be used to create a skeleton pure
+Perl module. See the B<-X> option.
+
+=head1 OPTIONS
+
+=over 5
+
+=item B<-A>, B<--omit-autoload>
+
+Omit all autoload facilities. This is the same as B<-c> but also
+removes the S<C<use AutoLoader>> statement from the .pm file.
+
+=item B<-B>, B<--beta-version>
+
+Use an alpha/beta style version number. Causes version number to
+be "0.00_01" unless B<-v> is specified.
+
+=item B<-C>, B<--omit-changes>
+
+Omits creation of the F<Changes> file, and adds a HISTORY section to
+the POD template.
+
+=item B<-F>, B<--cpp-flags>=I<addflags>
+
+Additional flags to specify to C preprocessor when scanning header for
+function declarations. Writes these options in the generated F<Makefile.PL>
+too.
+
+=item B<-M>, B<--func-mask>=I<regular expression>
+
+selects functions/macros to process.
+
+=item B<-O>, B<--overwrite-ok>
+
+Allows a pre-existing extension directory to be overwritten.
+
+=item B<-P>, B<--omit-pod>
+
+Omit the autogenerated stub POD section.
+
+=item B<-X>, B<--omit-XS>
+
+Omit the XS portion. Used to generate a skeleton pure Perl module.
+C<-c> and C<-f> are implicitly enabled.
+
+=item B<-a>, B<--gen-accessors>
+
+Generate an accessor method for each element of structs and unions. The
+generated methods are named after the element name; will return the current
+value of the element if called without additional arguments; and will set
+the element to the supplied value (and return the new value) if called with
+an additional argument. Embedded structures and unions are returned as a
+pointer rather than the complete structure, to facilitate chained calls.
+
+These methods all apply to the Ptr type for the structure; additionally
+two methods are constructed for the structure type itself, C<_to_ptr>
+which returns a Ptr type pointing to the same structure, and a C<new>
+method to construct and return a new structure, initialised to zeroes.
+
+=item B<-b>, B<--compat-version>=I<version>
+
+Generates a .pm file which is backwards compatible with the specified
+perl version.
+
+For versions < 5.6.0, the changes are.
+ - no use of 'our' (uses 'use vars' instead)
+ - no 'use warnings'
+
+Specifying a compatibility version higher than the version of perl you
+are using to run h2xs will have no effect. If unspecified h2xs will default
+to compatibility with the version of perl you are using to run h2xs.
+
+=item B<-c>, B<--omit-constant>
+
+Omit C<constant()> from the .xs file and corresponding specialised
+C<AUTOLOAD> from the .pm file.
+
+=item B<-d>, B<--debugging>
+
+Turn on debugging messages.
+
+=item B<-e>, B<--omit-enums>=[I<regular expression>]
+
+If I<regular expression> is not given, skip all constants that are defined in
+a C enumeration. Otherwise skip only those constants that are defined in an
+enum whose name matches I<regular expression>.
+
+Since I<regular expression> is optional, make sure that this switch is followed
+by at least one other switch if you omit I<regular expression> and have some
+pending arguments such as header-file names. This is ok:
+
+ h2xs -e -n Module::Foo foo.h
+
+This is not ok:
+
+ h2xs -n Module::Foo -e foo.h
+
+In the latter, foo.h is taken as I<regular expression>.
+
+=item B<-f>, B<--force>
+
+Allows an extension to be created for a header even if that header is
+not found in standard include directories.
+
+=item B<-g>, B<--global>
+
+Include code for safely storing static data in the .xs file.
+Extensions that do no make use of static data can ignore this option.
+
+=item B<-h>, B<-?>, B<--help>
+
+Print the usage, help and version for this h2xs and exit.
+
+=item B<-k>, B<--omit-const-func>
+
+For function arguments declared as C<const>, omit the const attribute in the
+generated XS code.
+
+=item B<-m>, B<--gen-tied-var>
+
+B<Experimental>: for each variable declared in the header file(s), declare
+a perl variable of the same name magically tied to the C variable.
+
+=item B<-n>, B<--name>=I<module_name>
+
+Specifies a name to be used for the extension, e.g., S<-n RPC::DCE>
+
+=item B<-o>, B<--opaque-re>=I<regular expression>
+
+Use "opaque" data type for the C types matched by the regular
+expression, even if these types are C<typedef>-equivalent to types
+from typemaps. Should not be used without B<-x>.
+
+This may be useful since, say, types which are C<typedef>-equivalent
+to integers may represent OS-related handles, and one may want to work
+with these handles in OO-way, as in C<$handle-E<gt>do_something()>.
+Use C<-o .> if you want to handle all the C<typedef>ed types as opaque
+types.
+
+The type-to-match is whitewashed (except for commas, which have no
+whitespace before them, and multiple C<*> which have no whitespace
+between them).
+
+=item B<-p>, B<--remove-prefix>=I<prefix>
+
+Specify a prefix which should be removed from the Perl function names,
+e.g., S<-p sec_rgy_> This sets up the XS B<PREFIX> keyword and removes
+the prefix from functions that are autoloaded via the C<constant()>
+mechanism.
+
+=item B<-s>, B<--const-subs>=I<sub1,sub2>
+
+Create a perl subroutine for the specified macros rather than autoload
+with the constant() subroutine. These macros are assumed to have a
+return type of B<char *>, e.g.,
+S<-s sec_rgy_wildcard_name,sec_rgy_wildcard_sid>.
+
+=item B<-t>, B<--default-type>=I<type>
+
+Specify the internal type that the constant() mechanism uses for macros.
+The default is IV (signed integer). Currently all macros found during the
+header scanning process will be assumed to have this type. Future versions
+of C<h2xs> may gain the ability to make educated guesses.
+
+=item B<--use-new-tests>
+
+When B<--compat-version> (B<-b>) is present the generated tests will use
+C<Test::More> rather than C<Test> which is the default for versions before
+5.7.2 . C<Test::More> will be added to PREREQ_PM in the generated
+C<Makefile.PL>.
+
+=item B<--use-old-tests>
+
+Will force the generation of test code that uses the older C<Test> module.
+
+=item B<--skip-exporter>
+
+Do not use C<Exporter> and/or export any symbol.
+
+=item B<--skip-ppport>
+
+Do not use C<Devel::PPPort>: no portability to older version.
+
+=item B<--skip-autoloader>
+
+Do not use the module C<AutoLoader>; but keep the constant() function
+and C<sub AUTOLOAD> for constants.
+
+=item B<--skip-strict>
+
+Do not use the pragma C<strict>.
+
+=item B<--skip-warnings>
+
+Do not use the pragma C<warnings>.
+
+=item B<-v>, B<--version>=I<version>
+
+Specify a version number for this extension. This version number is added
+to the templates. The default is 0.01, or 0.00_01 if C<-B> is specified.
+The version specified should be numeric.
+
+=item B<-x>, B<--autogen-xsubs>
+
+Automatically generate XSUBs basing on function declarations in the
+header file. The package C<C::Scan> should be installed. If this
+option is specified, the name of the header file may look like
+C<NAME1,NAME2>. In this case NAME1 is used instead of the specified
+string, but XSUBs are emitted only for the declarations included from
+file NAME2.
+
+Note that some types of arguments/return-values for functions may
+result in XSUB-declarations/typemap-entries which need
+hand-editing. Such may be objects which cannot be converted from/to a
+pointer (like C<long long>), pointers to functions, or arrays. See
+also the section on L<LIMITATIONS of B<-x>>.

+=head2 Extension based on F<.h> and F<.c> files
+
+Suppose that you have some C files implementing some functionality,
+and the corresponding header files. How to create an extension which
+makes this functionality accessible in Perl? The example below
+assumes that the header files are F<interface_simple.h> and
+I<interface_hairy.h>, and you want the perl module be named as
+C<Ext::Ension>. If you need some preprocessor directives and/or
+linking with external libraries, see the flags C<-F>, C<-L> and C<-l>
+in L<"OPTIONS">.
+
+=over
+
+=item Find the directory name
+
+Start with a dummy run of h2xs:
+
+ h2xs -Afn Ext::Ension
+
+The only purpose of this step is to create the needed directories, and
+let you know the names of these directories. From the output you can
+see that the directory for the extension is F<Ext/Ension>.
+
+=item Copy C files
+
+Copy your header files and C files to this directory F<Ext/Ension>.
+
+=item Create the extension
+
+Run h2xs, overwriting older autogenerated files:
+
+ h2xs -Oxan Ext::Ension interface_simple.h interface_hairy.h
+
+h2xs looks for header files I<after> changing to the extension
+directory, so it will find your header files OK.
+
+=item Archive and test
+
+As usual, run
+
+ cd Ext/Ension
+ perl Makefile.PL
+ make dist
+ make
+ make test
+
+=item Hints
+
+It is important to do C<make dist> as early as possible. This way you
+can easily merge(1) your changes to autogenerated files if you decide
+to edit your C<.h> files and rerun h2xs.
+
+Do not forget to edit the documentation in the generated F<.pm> file.
+
+Consider the autogenerated files as skeletons only, you may invent
+better interfaces than what h2xs could guess.
+
+Consider this section as a guideline only, some other options of h2xs
+may better suit your needs.

+
+The usual warnings if it cannot read or write the files involved.
+
+=head1 LIMITATIONS of B<-x>
+
+F<h2xs> would not distinguish whether an argument to a C function
+which is of the form, say, C<int *>, is an input, output, or
+input/output parameter. In particular, argument declarations of the
+form
+
+ int
+ foo(n)
+ int *n
+
+should be better rewritten as
+
+ int
+ foo(n)
+ int &n
+
+if C<n> is an input parameter.
+
+Additionally, F<h2xs> has no facilities to intuit that a function
+
+ int
+ foo(addr,l)
+ char *addr
+ int l
+
+takes a pair of address and length of data at this address, so it is better
+to rewrite this function as
+
+ int
+ foo(sv)
+ SV *addr
+ PREINIT:
+ STRLEN len;
+ char *s;
+ CODE:
+ s = SvPV(sv,len);
+ RETVAL = foo(s, len);
+ OUTPUT:
+ RETVAL
+
+or alternately
+
+ static int
+ my_foo(SV *sv)
+ {
+ STRLEN len;
+ char *s = SvPV(sv,len);
+
+ return foo(s, len);
+ }

+The README is used to introduce the module and provide instructions on

+example C compilers and installed libraries) and any other information
+that should be provided before the module is installed.
+
+A README file is required for CPAN modules since CPAN extracts the
+README file from a module distribution so that people browsing the
+archive can use it get an idea of the modules uses. It is usually a
+good idea to provide version information here so that people can
+decide whether fixes for the module are worth downloading.
