42 h2xs - convert .h C header files to Perl extensions
46 B<h2xs> [B<OPTIONS> ...] [headerfile ... [extra_libraries]]
48 B<h2xs> B<-h>|B<-?>|B<--help>
52 I<h2xs> builds a Perl extension from C header files. The extension
53 will include functions which can be used to retrieve the value of any
54 #define statement which was in the C header files.
56 The I<module_name> will be used for the name of the extension. If
57 module_name is not supplied then the name of the first header file
58 will be used, with the first character capitalized.
60 If the extension might need extra libraries, they should be included
61 here. The extension Makefile.PL will take care of checking whether
62 the libraries actually exist and how they should be loaded. The extra
63 libraries should be specified in the form -lm -lposix, etc, just as on
64 the cc command line. By default, the Makefile.PL will search through
65 the library path determined by Configure. That path can be augmented
66 by including arguments of the form B<-L/another/library/path> in the
67 extra-libraries argument.
73 =item B<-A>, B<--omit-autoload>
75 Omit all autoload facilities. This is the same as B<-c> but also
76 removes the S<C<use AutoLoader>> statement from the .pm file.
78 =item B<-C>, B<--omit-changes>
80 Omits creation of the F<Changes> file, and adds a HISTORY section to
83 =item B<-F>, B<--cpp-flags>=I<addflags>
85 Additional flags to specify to C preprocessor when scanning header for
86 function declarations. Should not be used without B<-x>.
88 =item B<-M>, B<--func-mask>=I<regular expression>
90 selects functions/macros to process.
92 =item B<-O>, B<--overwrite-ok>
94 Allows a pre-existing extension directory to be overwritten.
96 =item B<-P>, B<--omit-pod>
98 Omit the autogenerated stub POD section.
100 =item B<-X>, B<--omit-XS>
102 Omit the XS portion. Used to generate templates for a module which is not
103 XS-based. C<-c> and C<-f> are implicitly enabled.
105 =item B<-a>, B<--gen-accessors>
107 Generate an accessor method for each element of structs and unions. The
108 generated methods are named after the element name; will return the current
109 value of the element if called without additional arguments; and will set
110 the element to the supplied value (and return the new value) if called with
111 an additional argument. Embedded structures and unions are returned as a
112 pointer rather than the complete structure, to facilitate chained calls.
114 These methods all apply to the Ptr type for the structure; additionally
115 two methods are constructed for the structure type itself, C<_to_ptr>
116 which returns a Ptr type pointing to the same structure, and a C<new>
117 method to construct and return a new structure, initialised to zeroes.
119 =item B<-b>, B<--compat-version>=I<version>
121 Generates a .pm file which is backwards compatible with the specified
124 For versions < 5.6.0, the changes are.
125 - no use of 'our' (uses 'use vars' instead)
128 Specifying a compatibility version higher than the version of perl you
129 are using to run h2xs will have no effect.
131 =item B<-c>, B<--omit-constant>
133 Omit C<constant()> from the .xs file and corresponding specialised
134 C<AUTOLOAD> from the .pm file.
136 =item B<-d>, B<--debugging>
138 Turn on debugging messages.
140 =item B<-f>, B<--force>
142 Allows an extension to be created for a header even if that header is
143 not found in standard include directories.
145 =item B<-h>, B<-?>, B<--help>
147 Print the usage, help and version for this h2xs and exit.
149 =item B<-k>, B<--omit-const-func>
151 For function arguments declared as C<const>, omit the const attribute in the
154 =item B<-m>, B<--gen-tied-var>
156 B<Experimental>: for each variable declared in the header file(s), declare
157 a perl variable of the same name magically tied to the C variable.
159 =item B<-n>, B<--name>=I<module_name>
161 Specifies a name to be used for the extension, e.g., S<-n RPC::DCE>
163 =item B<-o>, B<--opaque-re>=I<regular expression>
165 Use "opaque" data type for the C types matched by the regular
166 expression, even if these types are C<typedef>-equivalent to types
167 from typemaps. Should not be used without B<-x>.
169 This may be useful since, say, types which are C<typedef>-equivalent
170 to integers may represent OS-related handles, and one may want to work
171 with these handles in OO-way, as in C<$handle-E<gt>do_something()>.
172 Use C<-o .> if you want to handle all the C<typedef>ed types as opaque
175 The type-to-match is whitewashed (except for commas, which have no
176 whitespace before them, and multiple C<*> which have no whitespace
179 =item B<-p>, B<--remove-prefix>=I<prefix>
181 Specify a prefix which should be removed from the Perl function names,
182 e.g., S<-p sec_rgy_> This sets up the XS B<PREFIX> keyword and removes
183 the prefix from functions that are autoloaded via the C<constant()>
186 =item B<-s>, B<--const-subs>=I<sub1,sub2>
188 Create a perl subroutine for the specified macros rather than autoload
189 with the constant() subroutine. These macros are assumed to have a
190 return type of B<char *>, e.g.,
191 S<-s sec_rgy_wildcard_name,sec_rgy_wildcard_sid>.
193 =item B<-t>, B<--default-type>=I<type>
195 Specify the internal type that the constant() mechanism uses for macros.
196 The default is IV (signed integer). Currently all macros found during the
197 header scanning process will be assumed to have this type. Future versions
198 of C<h2xs> may gain the ability to make educated guesses.
200 =item B<--use-new-tests>
202 When B<--compat-version> (B<-b>) is present the generated tests will use
203 C<Test::More> rather then C<Test> which is the default for versions before
204 5.7.2 . C<Test::More> will be added to PREREQ_PM in the generated
207 =item B<--use-old-tests>
209 Will force the generation of test code that uses the older C<Test> module.
211 =item B<-v>, B<--version>=I<version>
213 Specify a version number for this extension. This version number is added
214 to the templates. The default is 0.01.
216 =item B<-x>, B<--autogen-xsubs>
218 Automatically generate XSUBs basing on function declarations in the
219 header file. The package C<C::Scan> should be installed. If this
220 option is specified, the name of the header file may look like
221 C<NAME1,NAME2>. In this case NAME1 is used instead of the specified
222 string, but XSUBs are emitted only for the declarations included from
225 Note that some types of arguments/return-values for functions may
226 result in XSUB-declarations/typemap-entries which need
227 hand-editing. Such may be objects which cannot be converted from/to a
228 pointer (like C<long long>), pointers to functions, or arrays. See
229 also the section on L<LIMITATIONS of B<-x>>.

288 =head2 Extension based on F<.h> and F<.c> files
290 Suppose that you have some C files implementing some functionality,
291 and the corresponding header files. How to create an extension which
292 makes this functionality accessable in Perl? The example below
293 assumes that the header files are F<interface_simple.h> and
294 I<interface_hairy.h>, and you want the perl module be named as
295 C<Ext::Ension>. If you need some preprocessor directives and/or
296 linking with external libraries, see the flags C<-F>, C<-L> and C<-l>
301 =item Find the directory name
303 Start with a dummy run of h2xs:
305 h2xs -Afn Ext::Ension
307 The only purpose of this step is to create the needed directories, and
308 let you know the names of these directories. From the output you can
309 see that the directory for the extension is F<Ext/Ension>.
313 Copy your header files and C files to this directory F<Ext/Ension>.
315 =item Create the extension
317 Run h2xs, overwriting older autogenerated files:
319 h2xs -Oxan Ext::Ension interface_simple.h interface_hairy.h
321 h2xs looks for header files I<after> changing to the extension
322 directory, so it will find your header files OK.
324 =item Archive and test
336 It is important to do C<make dist> as early as possible. This way you
337 can easily merge(1) your changes to autogenerated files if you decide
338 to edit your C<.h> files and rerun h2xs.
340 Do not forget to edit the documentation in the generated F<.pm> file.
342 Consider the autogenerated files as skeletons only, you may invent
343 better interfaces than what h2xs could guess.
345 Consider this section as a guideline only, some other options of h2xs
346 may better suit your needs.
352 No environment variables are used.

366 =head1 LIMITATIONS of B<-x>
368 F<h2xs> would not distinguish whether an argument to a C function
369 which is of the form, say, C<int *>, is an input, output, or
370 input/output parameter. In particular, argument declarations of the
377 should be better rewritten as
383 if C<n> is an input parameter.
385 Additionally, F<h2xs> has no facilities to intuit that a function
392 takes a pair of address and length of data at this address, so it is better
393 to rewrite this function as
403 RETVAL = foo(s, len);
413 char *s = SvPV(sv,len);
418 MODULE = foo PACKAGE = foo PREFIX = my_

1799 The README is used to introduce the module and provide instructions on
1800 how to install the module, any machine dependencies it may have (for
1801 example C compilers and installed libraries) and any other information
1802 that should be provided before the module is installed.
1804 A README file is required for CPAN modules since CPAN extracts the
1805 README file from a module distribution so that people browsing the
1806 archive can use it get an idea of the modules uses. It is usually a
1807 good idea to provide version information here so that people can
1808 decide whether fixes for the module are worth downloading.
