40 | =head1 NAME |
41 | |
42 | h2xs - convert .h C header files to Perl extensions |
43 | |
44 | =head1 SYNOPSIS |
45 | |
11946041 |
46 | B<h2xs> [B<OPTIONS> ...] [headerfile ... [extra_libraries]] |

50 | =head1 DESCRIPTION |
51 | |
a887ff11 |
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. |
3edbfbe5 |
55 | |
56 | The I<module_name> will be used for the name of the extension. If |
a887ff11 |
57 | module_name is not supplied then the name of the first header file |
58 | will be used, with the first character capitalized. |
3edbfbe5 |
59 | |
60 | If the extension might need extra libraries, they should be included |
61 | here. The extension Makefile.PL will take care of checking whether |
9cacc32e |
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> |
3edbfbe5 |
74 | |
9cacc32e |
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. |
3edbfbe5 |
77 | |
4d2d0db2 |
78 | =item B<-C>, B<--omit-changes> |
c0f8b9cd |
79 | |
80 | Omits creation of the F<Changes> file, and adds a HISTORY section to |
81 | the POD template. |
82 | |
4d2d0db2 |
83 | =item B<-F>, B<--cpp-flags>=I<addflags> |
b73edd97 |
84 | |
85 | Additional flags to specify to C preprocessor when scanning header for |
ddf6bed1 |
86 | function declarations. Should not be used without B<-x>. |
87 | |
4d2d0db2 |
88 | =item B<-M>, B<--func-mask>=I<regular expression> |
ddf6bed1 |
89 | |
90 | selects functions/macros to process. |
b73edd97 |
91 | |
4d2d0db2 |
92 | =item B<-O>, B<--overwrite-ok> |
2920c5d2 |
93 | |
94 | Allows a pre-existing extension directory to be overwritten. |
95 | |
4d2d0db2 |
96 | =item B<-P>, B<--omit-pod> |
3edbfbe5 |
97 | |
f508c652 |
98 | Omit the autogenerated stub POD section. |
3edbfbe5 |
99 | |
4d2d0db2 |
100 | =item B<-X>, B<--omit-XS> |
b73edd97 |
101 | |
102 | Omit the XS portion. Used to generate templates for a module which is not |
9ef261b5 |
103 | XS-based. C<-c> and C<-f> are implicitly enabled. |
b73edd97 |
104 | |
4d2d0db2 |
105 | =item B<-a>, B<--gen-accessors> |
7c1d48a5 |
106 | |
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 |
32fb2b78 |
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. |
113 | |
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. |
7c1d48a5 |
118 | |
4d2d0db2 |
119 | =item B<-b>, B<--compat-version>=I<version> |
af6c647e |
120 | |
121 | Generates a .pm file which is backwards compatible with the specified |
122 | perl version. |
123 | |
124 | For versions < 5.6.0, the changes are. |
125 | - no use of 'our' (uses 'use vars' instead) |
126 | - no 'use warnings' |
127 | |
128 | Specifying a compatibility version higher than the version of perl you |
129 | are using to run h2xs will have no effect. |
130 | |
4d2d0db2 |
131 | =item B<-c>, B<--omit-constant> |
3edbfbe5 |
132 | |
133 | Omit C<constant()> from the .xs file and corresponding specialised |
134 | C<AUTOLOAD> from the .pm file. |
135 | |
4d2d0db2 |
136 | =item B<-d>, B<--debugging> |
b73edd97 |
137 | |
138 | Turn on debugging messages. |
139 | |
4d2d0db2 |
140 | =item B<-f>, B<--force> |
3edbfbe5 |
141 | |
f508c652 |
142 | Allows an extension to be created for a header even if that header is |
ddf6bed1 |
143 | not found in standard include directories. |
f508c652 |
144 | |
4d2d0db2 |
145 | =item B<-h>, B<-?>, B<--help> |
f508c652 |
146 | |
147 | Print the usage, help and version for this h2xs and exit. |
148 | |
4d2d0db2 |
149 | =item B<-k>, B<--omit-const-func> |
32fb2b78 |
150 | |
151 | For function arguments declared as C<const>, omit the const attribute in the |
152 | generated XS code. |
153 | |
4d2d0db2 |
154 | =item B<-m>, B<--gen-tied-var> |
32fb2b78 |
155 | |
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. |
158 | |
4d2d0db2 |
159 | =item B<-n>, B<--name>=I<module_name> |
f508c652 |
160 | |
161 | Specifies a name to be used for the extension, e.g., S<-n RPC::DCE> |
162 | |
4d2d0db2 |
163 | =item B<-o>, B<--opaque-re>=I<regular expression> |
ddf6bed1 |
164 | |
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>. |
168 | |
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()>. |
9cacc32e |
172 | Use C<-o .> if you want to handle all the C<typedef>ed types as opaque |
173 | types. |
ddf6bed1 |
174 | |
175 | The type-to-match is whitewashed (except for commas, which have no |
176 | whitespace before them, and multiple C<*> which have no whitespace |
177 | between them). |
178 | |
4d2d0db2 |
179 | =item B<-p>, B<--remove-prefix>=I<prefix> |
ead2a595 |
180 | |
9cacc32e |
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()> |
184 | mechanism. |
ead2a595 |
185 | |
4d2d0db2 |
186 | =item B<-s>, B<--const-subs>=I<sub1,sub2> |
ead2a595 |
187 | |
9cacc32e |
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>. |
ead2a595 |
192 | |
4d2d0db2 |
193 | =item B<-t>, B<--default-type>=I<type> |
af6c647e |
194 | |
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. |
199 | |
11946041 |
200 | =item B<--use-new-tests> |
201 | |
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 |
205 | C<Makefile.PL>. |
206 | |
207 | =item B<--use-old-tests> |
208 | |
209 | Will force the generation of test code that uses the older C<Test> module. |
210 | |
4d2d0db2 |
211 | =item B<-v>, B<--version>=I<version> |
f508c652 |
212 | |
213 | Specify a version number for this extension. This version number is added |
214 | to the templates. The default is 0.01. |
3edbfbe5 |
215 | |
4d2d0db2 |
216 | =item B<-x>, B<--autogen-xsubs> |
760ac839 |
217 | |
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 |
9cacc32e |
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 |
223 | file NAME2. |
760ac839 |
224 | |
5273d82d |
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 |
ddf6bed1 |
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 |
289 | |
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> |
297 | in L<"OPTIONS">. |
298 | |
299 | =over |
300 | |
301 | =item Find the directory name |
302 | |
303 | Start with a dummy run of h2xs: |
304 | |
305 | h2xs -Afn Ext::Ension |
306 | |
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>. |
310 | |
311 | =item Copy C files |
312 | |
313 | Copy your header files and C files to this directory F<Ext/Ension>. |
314 | |
315 | =item Create the extension |
316 | |
317 | Run h2xs, overwriting older autogenerated files: |
318 | |
319 | h2xs -Oxan Ext::Ension interface_simple.h interface_hairy.h |
320 | |
321 | h2xs looks for header files I<after> changing to the extension |
322 | directory, so it will find your header files OK. |
323 | |
324 | =item Archive and test |
325 | |
326 | As usual, run |
327 | |
328 | cd Ext/Ension |
329 | perl Makefile.PL |
330 | make dist |
331 | make |
332 | make test |
333 | |
334 | =item Hints |
335 | |
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. |
339 | |
340 | Do not forget to edit the documentation in the generated F<.pm> file. |
341 | |
342 | Consider the autogenerated files as skeletons only, you may invent |
343 | better interfaces than what h2xs could guess. |
344 | |
345 | Consider this section as a guideline only, some other options of h2xs |
346 | may better suit your needs. |

366 | =head1 LIMITATIONS of B<-x> |
367 | |
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 |
371 | form |
372 | |
373 | int |
374 | foo(n) |
375 | int *n |
376 | |
377 | should be better rewritten as |
378 | |
379 | int |
380 | foo(n) |
381 | int &n |
382 | |
383 | if C<n> is an input parameter. |
384 | |
385 | Additionally, F<h2xs> has no facilities to intuit that a function |
386 | |
387 | int |
388 | foo(addr,l) |
389 | char *addr |
390 | int l |
391 | |
392 | takes a pair of address and length of data at this address, so it is better |
393 | to rewrite this function as |
394 | |
395 | int |
396 | foo(sv) |

397 | SV *addr |
398 | PREINIT: |

451 | -A, --omit-autoload Omit all autoloading facilities (implies -c). |
452 | -C, --omit-changes Omit creating the Changes file, add HISTORY heading |
453 | to stub POD. |
454 | -F, --cpp-flags Additional flags for C preprocessor (used with -x). |
455 | -M, --func-mask Mask to select C functions/macros |
456 | (default is select all). |
457 | -O, --overwrite-ok Allow overwriting of a pre-existing extension directory. |
458 | -P, --omit-pod Omit the stub POD section. |
459 | -X, --omit-XS Omit the XS portion (implies both -c and -f). |
460 | -a, --gen-accessors Generate get/set accessors for struct and union members (used with -x). |
461 | -b, --compat-version Specify a perl version to be backwards compatibile with |
462 | -c, --omit-constant Omit the constant() function and specialised AUTOLOAD |
463 | from the XS file. |
464 | -d, --debugging Turn on debugging messages. |
465 | -f, --force Force creation of the extension even if the C header |
466 | does not exist. |
467 | -h, -?, --help Display this help message |
468 | -k, --omit-const-func Omit 'const' attribute on function arguments |
469 | (used with -x). |
470 | -m, --gen-tied-var Generate tied variables for access to declared |
471 | variables. |
472 | -n, --name Specify a name to use for the extension (recommended). |
473 | -o, --opaque-re Regular expression for \"opaque\" types. |
474 | -p, --remove-prefix Specify a prefix which should be removed from the |
475 | Perl function names. |
476 | -s, --const-subs Create subroutines for specified macros. |
9a7df4f2 |
477 | -t, --default-type Default type for autoloaded constants (default is IV) |
11946041 |
478 | --use-new-tests Use Test::More in backward compatible modules |
479 | --use-old-tests Use the module Test rather than Test::More |
4d2d0db2 |
480 | -v, --version Specify a version number for this extension. |
481 | -x, --autogen-xsubs Autogenerate XSUBs using C::Scan. |
482 | |
e1666bf5 |
483 | extra_libraries |
484 | are any libraries that might be needed for loading the |
485 | extension, e.g. -lm would try to link in the math library. |

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. |
1803 | |
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. |
1809 | |
