42h2xs - convert .h C header files to Perl extensions
43
44=head1 SYNOPSIS
45
46B<h2xs> [B<OPTIONS> ...] [headerfile ... [extra_libraries]]
47
48B<h2xs> B<-h>|B<-?>|B<--help>
49
50=head1 DESCRIPTION
51
52I<h2xs> builds a Perl extension from C header files. The extension
53will include functions which can be used to retrieve the value of any
54#define statement which was in the C header files.
55
56The I<module_name> will be used for the name of the extension. If
57module_name is not supplied then the name of the first header file
58will be used, with the first character capitalized.
59
60If the extension might need extra libraries, they should be included
61here. The extension Makefile.PL will take care of checking whether
62the libraries actually exist and how they should be loaded. The extra
63libraries should be specified in the form -lm -lposix, etc, just as on
64the cc command line. By default, the Makefile.PL will search through
65the library path determined by Configure. That path can be augmented
66by including arguments of the form B<-L/another/library/path> in the
67extra-libraries argument.
68
69=head1 OPTIONS
70
71=over 5
72
73=item B<-A>, B<--omit-autoload>
74
75Omit all autoload facilities. This is the same as B<-c> but also
76removes the S<C<use AutoLoader>> statement from the .pm file.
77
78=item B<-B>, B<--beta-version>
79
80Use an alpha/beta style version number. Causes version number to
81be "0.00_01" unless B<-v> is specified.
82
83=item B<-C>, B<--omit-changes>
84
85Omits creation of the F<Changes> file, and adds a HISTORY section to
86the POD template.
87
88=item B<-F>, B<--cpp-flags>=I<addflags>
89
90Additional flags to specify to C preprocessor when scanning header for
91function declarations. Writes these options in the generated F<Makefile.PL>
92too.
93
94=item B<-M>, B<--func-mask>=I<regular expression>
95
96selects functions/macros to process.
97
98=item B<-O>, B<--overwrite-ok>
99
100Allows a pre-existing extension directory to be overwritten.
101
102=item B<-P>, B<--omit-pod>
103
104Omit the autogenerated stub POD section.
105
106=item B<-X>, B<--omit-XS>
107
108Omit the XS portion. Used to generate templates for a module which is not
109XS-based. C<-c> and C<-f> are implicitly enabled.
110
111=item B<-a>, B<--gen-accessors>
112
113Generate an accessor method for each element of structs and unions. The
114generated methods are named after the element name; will return the current
115value of the element if called without additional arguments; and will set
116the element to the supplied value (and return the new value) if called with
117an additional argument. Embedded structures and unions are returned as a
118pointer rather than the complete structure, to facilitate chained calls.
119
120These methods all apply to the Ptr type for the structure; additionally
121two methods are constructed for the structure type itself, C<_to_ptr>
122which returns a Ptr type pointing to the same structure, and a C<new>
123method to construct and return a new structure, initialised to zeroes.
124
125=item B<-b>, B<--compat-version>=I<version>
126
127Generates a .pm file which is backwards compatible with the specified
128perl version.
129
130For versions < 5.6.0, the changes are.
131 - no use of 'our' (uses 'use vars' instead)
132 - no 'use warnings'
133
134Specifying a compatibility version higher than the version of perl you
135are using to run h2xs will have no effect. If unspecified h2xs will default
136to compatibility with the version of perl you are using to run h2xs.
137
138=item B<-c>, B<--omit-constant>
139
140Omit C<constant()> from the .xs file and corresponding specialised
141C<AUTOLOAD> from the .pm file.
142
143=item B<-d>, B<--debugging>
144
145Turn on debugging messages.
146
147=item B<-e>, B<--omit-enums>=[I<regular expression>]
148
149If I<regular expression> is not given, skip all constants that are defined in
150a C enumeration. Otherwise skip only those constants that are defined in an
151enum whose name matches I<regular expression>.
152
153Since I<regular expression> is optional, make sure that this switch is followed
154by at least one other switch if you omit I<regular expression> and have some
155pending arguments such as header-file names. This is ok:
156
157 h2xs -e -n Module::Foo foo.h
158
159This is not ok:
160
161 h2xs -n Module::Foo -e foo.h
162
163In the latter, foo.h is taken as I<regular expression>.
164
165=item B<-f>, B<--force>
166
167Allows an extension to be created for a header even if that header is
168not found in standard include directories.
169
170=item B<-g>, B<--global>
171
172Include code for safely storing static data in the .xs file.
173Extensions that do no make use of static data can ignore this option.
174
175=item B<-h>, B<-?>, B<--help>
176
177Print the usage, help and version for this h2xs and exit.
178
179=item B<-k>, B<--omit-const-func>
180
181For function arguments declared as C<const>, omit the const attribute in the
182generated XS code.
183
184=item B<-m>, B<--gen-tied-var>
185
186B<Experimental>: for each variable declared in the header file(s), declare
187a perl variable of the same name magically tied to the C variable.
188
189=item B<-n>, B<--name>=I<module_name>
190
191Specifies a name to be used for the extension, e.g., S<-n RPC::DCE>
192
193=item B<-o>, B<--opaque-re>=I<regular expression>
194
195Use "opaque" data type for the C types matched by the regular
196expression, even if these types are C<typedef>-equivalent to types
197from typemaps. Should not be used without B<-x>.
198
199This may be useful since, say, types which are C<typedef>-equivalent
200to integers may represent OS-related handles, and one may want to work
201with these handles in OO-way, as in C<$handle-E<gt>do_something()>.
202Use C<-o .> if you want to handle all the C<typedef>ed types as opaque
203types.
204
205The type-to-match is whitewashed (except for commas, which have no
206whitespace before them, and multiple C<*> which have no whitespace
207between them).
208
209=item B<-p>, B<--remove-prefix>=I<prefix>
210
211Specify a prefix which should be removed from the Perl function names,
212e.g., S<-p sec_rgy_> This sets up the XS B<PREFIX> keyword and removes
213the prefix from functions that are autoloaded via the C<constant()>
214mechanism.
215
216=item B<-s>, B<--const-subs>=I<sub1,sub2>
217
218Create a perl subroutine for the specified macros rather than autoload
219with the constant() subroutine. These macros are assumed to have a
220return type of B<char *>, e.g.,
221S<-s sec_rgy_wildcard_name,sec_rgy_wildcard_sid>.
222
223=item B<-t>, B<--default-type>=I<type>
224
225Specify the internal type that the constant() mechanism uses for macros.
226The default is IV (signed integer). Currently all macros found during the
227header scanning process will be assumed to have this type. Future versions
228of C<h2xs> may gain the ability to make educated guesses.
229
230=item B<--use-new-tests>
231
232When B<--compat-version> (B<-b>) is present the generated tests will use
233C<Test::More> rather than C<Test> which is the default for versions before
2345.7.2 . C<Test::More> will be added to PREREQ_PM in the generated
235C<Makefile.PL>.
236
237=item B<--use-old-tests>
238
239Will force the generation of test code that uses the older C<Test> module.
240
241=item B<--skip-exporter>
242
243Do not use C<Exporter> and/or export any symbol.
244
245=item B<--skip-ppport>
246
247Do not use C<Devel::PPPort>: no portability to older version.
248
249=item B<--skip-autoloader>
250
251Do not use the module C<AutoLoader>; but keep the constant() function
252and C<sub AUTOLOAD> for constants.
253
254=item B<--skip-strict>
255
256Do not use the pragma C<strict>.
257
258=item B<--skip-warnings>
259
260Do not use the pragma C<warnings>.
261
262=item B<-v>, B<--version>=I<version>
263
264Specify a version number for this extension. This version number is added
265to the templates. The default is 0.01, or 0.00_01 if C<-B> is specified.
266The version specified should be numeric.
267
268=item B<-x>, B<--autogen-xsubs>
269
270Automatically generate XSUBs basing on function declarations in the
271header file. The package C<C::Scan> should be installed. If this
272option is specified, the name of the header file may look like
273C<NAME1,NAME2>. In this case NAME1 is used instead of the specified
274string, but XSUBs are emitted only for the declarations included from
275file NAME2.
276
277Note that some types of arguments/return-values for functions may
278result in XSUB-declarations/typemap-entries which need
279hand-editing. Such may be objects which cannot be converted from/to a
280pointer (like C<long long>), pointers to functions, or arrays. See
281also the section on L<LIMITATIONS of B<-x>>.

351=head2 Extension based on F<.h> and F<.c> files
352
353Suppose that you have some C files implementing some functionality,
354and the corresponding header files. How to create an extension which
355makes this functionality accessible in Perl? The example below
356assumes that the header files are F<interface_simple.h> and
357I<interface_hairy.h>, and you want the perl module be named as
358C<Ext::Ension>. If you need some preprocessor directives and/or
359linking with external libraries, see the flags C<-F>, C<-L> and C<-l>
360in L<"OPTIONS">.
361
362=over
363
364=item Find the directory name
365
366Start with a dummy run of h2xs:
367
368 h2xs -Afn Ext::Ension
369
370The only purpose of this step is to create the needed directories, and
371let you know the names of these directories. From the output you can
372see that the directory for the extension is F<Ext/Ension>.
373
374=item Copy C files
375
376Copy your header files and C files to this directory F<Ext/Ension>.
377
378=item Create the extension
379
380Run h2xs, overwriting older autogenerated files:
381
382 h2xs -Oxan Ext::Ension interface_simple.h interface_hairy.h
383
384h2xs looks for header files I<after> changing to the extension
385directory, so it will find your header files OK.
386
387=item Archive and test
388
389As usual, run
390
391 cd Ext/Ension
392 perl Makefile.PL
393 make dist
394 make
395 make test
396
397=item Hints
398
399It is important to do C<make dist> as early as possible. This way you
400can easily merge(1) your changes to autogenerated files if you decide
401to edit your C<.h> files and rerun h2xs.
402
403Do not forget to edit the documentation in the generated F<.pm> file.
404
405Consider the autogenerated files as skeletons only, you may invent
406better interfaces than what h2xs could guess.
407
408Consider this section as a guideline only, some other options of h2xs
409may better suit your needs.

429=head1 LIMITATIONS of B<-x>
430
431F<h2xs> would not distinguish whether an argument to a C function
432which is of the form, say, C<int *>, is an input, output, or
433input/output parameter. In particular, argument declarations of the
434form
435
436 int
437 foo(n)
438 int *n
439
440should be better rewritten as
441
442 int
443 foo(n)
444 int &n
445
446if C<n> is an input parameter.
447
448Additionally, F<h2xs> has no facilities to intuit that a function
449
450 int
451 foo(addr,l)
452 char *addr
453 int l
454
455takes a pair of address and length of data at this address, so it is better
456to rewrite this function as
457
458 int
459 foo(sv)
460 SV *addr
461 PREINIT:
462 STRLEN len;
463 char *s;
464 CODE:
465 s = SvPV(sv,len);
466 RETVAL = foo(s, len);
467 OUTPUT:

469
470or alternately
471
472 static int
473 my_foo(SV *sv)
474 {

2029The README is used to introduce the module and provide instructions on
2030how to install the module, any machine dependencies it may have (for
2031example C compilers and installed libraries) and any other information
2032that should be provided before the module is installed.
2033
2034A README file is required for CPAN modules since CPAN extracts the
2035README file from a module distribution so that people browsing the
2036archive can use it get an idea of the modules uses. It is usually a
2037good idea to provide version information here so that people can
2038decide whether fixes for the module are worth downloading.
