=head1 DESCRIPTION
-I<h2xs> builds a Perl extension from any C header file. The extension will
-include functions which can be used to retrieve the value of any #define
-statement which was in the C header.
+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 header file will be used,
-with the first character capitalized.
+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
Omit all autoload facilities. This is the same as B<-c> but also removes the
S<C<require AutoLoader>> statement from the .pm file.
+=item B<-F>
+
+Additional flags to specify to C preprocessor when scanning header for
+function declarations. Should not be used without B<-x>.
+
+=item B<-O>
+
+Allows a pre-existing extension directory to be overwritten.
+
=item B<-P>
Omit the autogenerated stub POD section.
+=item B<-X>
+
+Omit the XS portion. Used to generate templates for a module which is not
+XS-based.
+
=item B<-c>
Omit C<constant()> from the .xs file and corresponding specialised
C<AUTOLOAD> from the .pm file.
+=item B<-d>
+
+Turn on debugging messages.
+
=item B<-f>
Allows an extension to be created for a header even if that header is
Specifies a name to be used for the extension, e.g., S<-n RPC::DCE>
+=item B<-p> 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()> mechansim.
+
+=item B<-s> 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<-v> I<version>
Specify a version number for this extension. This version number is added
to the templates. The default is 0.01.
+=item B<-x>
+
+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.
