48 | =head1 DESCRIPTION |
49 | |
a887ff11 |
50 | I<h2xs> builds a Perl extension from C header files. The extension |
51 | will include functions which can be used to retrieve the value of any |
52 | #define statement which was in the C header files. |
3edbfbe5 |
53 | |
54 | The I<module_name> will be used for the name of the extension. If |
a887ff11 |
55 | module_name is not supplied then the name of the first header file |
56 | will be used, with the first character capitalized. |
3edbfbe5 |
57 | |
58 | If the extension might need extra libraries, they should be included |
59 | here. The extension Makefile.PL will take care of checking whether |
60 | the libraries actually exist and how they should be loaded. |
61 | The extra libraries should be specified in the form -lm -lposix, etc, |
62 | just as on the cc command line. By default, the Makefile.PL will |
63 | search through the library path determined by Configure. That path |
64 | can be augmented by including arguments of the form B<-L/another/library/path> |
65 | in the extra-libraries argument. |

72 | |
f508c652 |
73 | Omit all autoload facilities. This is the same as B<-c> but also removes the |
9ef261b5 |
74 | S<C<use AutoLoader>> statement from the .pm file. |
3edbfbe5 |

77 | |
78 | Omits creation of the F<Changes> file, and adds a HISTORY section to |
79 | the POD template. |
80 | |
be3174d2 |
81 | =item B<-F> I<addflags> |
b73edd97 |
82 | |
83 | Additional flags to specify to C preprocessor when scanning header for |
ddf6bed1 |
84 | function declarations. Should not be used without B<-x>. |
85 | |
86 | =item B<-M> I<regular expression> |
87 | |
88 | selects functions/macros to process. |
b73edd97 |

92 | Allows a pre-existing extension directory to be overwritten. |
93 | |
f508c652 |
94 | =item B<-P> |

95 | |
f508c652 |
96 | Omit the autogenerated stub POD section. |
3edbfbe5 |
97 | |
b73edd97 |
98 | =item B<-X> |
99 | |
100 | Omit the XS portion. Used to generate templates for a module which is not |
9ef261b5 |
101 | XS-based. C<-c> and C<-f> are implicitly enabled. |
b73edd97 |
102 | |
7c1d48a5 |
103 | =item B<-a> |
104 | |
105 | Generate an accessor method for each element of structs and unions. The |
106 | generated methods are named after the element name; will return the current |
107 | value of the element if called without additional arguments; and will set |
32fb2b78 |
108 | the element to the supplied value (and return the new value) if called with |
109 | an additional argument. Embedded structures and unions are returned as a |
110 | pointer rather than the complete structure, to facilitate chained calls. |
111 | |
112 | These methods all apply to the Ptr type for the structure; additionally |
113 | two methods are constructed for the structure type itself, C<_to_ptr> |
114 | which returns a Ptr type pointing to the same structure, and a C<new> |
115 | method to construct and return a new structure, initialised to zeroes. |
7c1d48a5 |
116 | |
3edbfbe5 |
117 | =item B<-c> |
118 | |
119 | Omit C<constant()> from the .xs file and corresponding specialised |
120 | C<AUTOLOAD> from the .pm file. |
121 | |
b73edd97 |
122 | =item B<-d> |
123 | |
124 | Turn on debugging messages. |
125 | |
f508c652 |
126 | =item B<-f> |
3edbfbe5 |
127 | |
f508c652 |
128 | Allows an extension to be created for a header even if that header is |
ddf6bed1 |
129 | not found in standard include directories. |
f508c652 |
130 | |
131 | =item B<-h> |
132 | |
133 | Print the usage, help and version for this h2xs and exit. |
134 | |
32fb2b78 |
135 | =item B<-k> |
136 | |
137 | For function arguments declared as C<const>, omit the const attribute in the |
138 | generated XS code. |
139 | |
140 | =item B<-m> |
141 | |
142 | B<Experimental>: for each variable declared in the header file(s), declare |
143 | a perl variable of the same name magically tied to the C variable. |
144 | |
f508c652 |
145 | =item B<-n> I<module_name> |
146 | |
147 | Specifies a name to be used for the extension, e.g., S<-n RPC::DCE> |
148 | |
ddf6bed1 |
149 | =item B<-o> I<regular expression> |
150 | |
151 | Use "opaque" data type for the C types matched by the regular |
152 | expression, even if these types are C<typedef>-equivalent to types |
153 | from typemaps. Should not be used without B<-x>. |
154 | |
155 | This may be useful since, say, types which are C<typedef>-equivalent |
156 | to integers may represent OS-related handles, and one may want to work |
157 | with these handles in OO-way, as in C<$handle-E<gt>do_something()>. |
158 | Use C<-o .> if you want to handle all the C<typedef>ed types as opaque types. |
159 | |
160 | The type-to-match is whitewashed (except for commas, which have no |
161 | whitespace before them, and multiple C<*> which have no whitespace |
162 | between them). |
163 | |
ead2a595 |
164 | =item B<-p> I<prefix> |
165 | |
166 | Specify a prefix which should be removed from the Perl function names, e.g., S<-p sec_rgy_> |
167 | This sets up the XS B<PREFIX> keyword and removes the prefix from functions that are |
98a6f11e |
168 | autoloaded via the C<constant()> mechanism. |
ead2a595 |
169 | |
170 | =item B<-s> I<sub1,sub2> |
171 | |
172 | Create a perl subroutine for the specified macros rather than autoload with the constant() subroutine. |
173 | These macros are assumed to have a return type of B<char *>, e.g., S<-s sec_rgy_wildcard_name,sec_rgy_wildcard_sid>. |
174 | |
f508c652 |
175 | =item B<-v> I<version> |
176 | |
177 | Specify a version number for this extension. This version number is added |
178 | to the templates. The default is 0.01. |
3edbfbe5 |
179 | |
760ac839 |
180 | =item B<-x> |
181 | |
182 | Automatically generate XSUBs basing on function declarations in the |
183 | header file. The package C<C::Scan> should be installed. If this |
184 | option is specified, the name of the header file may look like |
185 | C<NAME1,NAME2>. In this case NAME1 is used instead of the specified string, |
b73edd97 |
186 | but XSUBs are emitted only for the declarations included from file NAME2. |
760ac839 |
187 | |
5273d82d |
188 | Note that some types of arguments/return-values for functions may |
189 | result in XSUB-declarations/typemap-entries which need |
190 | hand-editing. Such may be objects which cannot be converted from/to a |
ddf6bed1 |
191 | pointer (like C<long long>), pointers to functions, or arrays. See |
192 | also the section on L<LIMITATIONS of B<-x>>. |
5273d82d |
193 | |
be3174d2 |
194 | =item B<-b> I<version> |
195 | |
196 | Generates a .pm file which is backwards compatible with the specified |
197 | perl version. |
198 | |
199 | For versions < 5.6.0, the changes are. |
200 | - no use of 'our' (uses 'use vars' instead) |
201 | - no 'use warnings' |
202 | |
203 | Specifying a compatibility version higher than the version of perl you |
204 | are using to run h2xs will have no effect. |

263 | =head2 Extension based on F<.h> and F<.c> files |
264 | |
265 | Suppose that you have some C files implementing some functionality, |
266 | and the corresponding header files. How to create an extension which |
267 | makes this functionality accessable in Perl? The example below |
268 | assumes that the header files are F<interface_simple.h> and |
269 | I<interface_hairy.h>, and you want the perl module be named as |
270 | C<Ext::Ension>. If you need some preprocessor directives and/or |
271 | linking with external libraries, see the flags C<-F>, C<-L> and C<-l> |
272 | in L<"OPTIONS">. |
273 | |
274 | =over |
275 | |
276 | =item Find the directory name |
277 | |
278 | Start with a dummy run of h2xs: |
279 | |
280 | h2xs -Afn Ext::Ension |
281 | |
282 | The only purpose of this step is to create the needed directories, and |
283 | let you know the names of these directories. From the output you can |
284 | see that the directory for the extension is F<Ext/Ension>. |
285 | |
286 | =item Copy C files |
287 | |
288 | Copy your header files and C files to this directory F<Ext/Ension>. |
289 | |
290 | =item Create the extension |
291 | |
292 | Run h2xs, overwriting older autogenerated files: |
293 | |
294 | h2xs -Oxan Ext::Ension interface_simple.h interface_hairy.h |
295 | |
296 | h2xs looks for header files I<after> changing to the extension |
297 | directory, so it will find your header files OK. |
298 | |
299 | =item Archive and test |
300 | |
301 | As usual, run |
302 | |
303 | cd Ext/Ension |
304 | perl Makefile.PL |
305 | make dist |
306 | make |
307 | make test |
308 | |
309 | =item Hints |
310 | |
311 | It is important to do C<make dist> as early as possible. This way you |
312 | can easily merge(1) your changes to autogenerated files if you decide |
313 | to edit your C<.h> files and rerun h2xs. |
314 | |
315 | Do not forget to edit the documentation in the generated F<.pm> file. |
316 | |
317 | Consider the autogenerated files as skeletons only, you may invent |
318 | better interfaces than what h2xs could guess. |
319 | |
320 | Consider this section as a guideline only, some other options of h2xs |
321 | may better suit your needs. |

341 | =head1 LIMITATIONS of B<-x> |
342 | |
343 | F<h2xs> would not distinguish whether an argument to a C function |
344 | which is of the form, say, C<int *>, is an input, output, or |
345 | input/output parameter. In particular, argument declarations of the |
346 | form |
347 | |
348 | int |
349 | foo(n) |
350 | int *n |
351 | |
352 | should be better rewritten as |
353 | |
354 | int |
355 | foo(n) |
356 | int &n |
357 | |
358 | if C<n> is an input parameter. |
359 | |
360 | Additionally, F<h2xs> has no facilities to intuit that a function |
361 | |
362 | int |
363 | foo(addr,l) |
364 | char *addr |
365 | int l |
366 | |
367 | takes a pair of address and length of data at this address, so it is better |
368 | to rewrite this function as |
369 | |
370 | int |
371 | foo(sv) |
7aff18a2 |
372 | SV *addr |
373 | PREINIT: |

1775 | The README is used to introduce the module and provide instructions on |
1776 | how to install the module, any machine dependencies it may have (for |
1777 | example C compilers and installed libraries) and any other information |
1778 | that should be provided before the module is installed. |

1780 | A README file is required for CPAN modules since CPAN extracts the |
1781 | README file from a module distribution so that people browsing the |
1782 | archive can use it get an idea of the modules uses. It is usually a |
1783 | good idea to provide version information here so that people can |
1784 | decide whether fixes for the module are worth downloading. |
