5 | xsubpp - compiler to convert Perl XS code into C code |
6 | |
7 | =head1 SYNOPSIS |
8 | |
c5be433b |
9 | B<xsubpp> [B<-v>] [B<-C++>] [B<-except>] [B<-s pattern>] [B<-prototypes>] [B<-noversioncheck>] [B<-nolinenumbers>] [B<-typemap typemap>] ... file.xs |
75f92628 |
10 | |
11 | =head1 DESCRIPTION |
12 | |
13 | I<xsubpp> will compile XS code into C code by embedding the constructs |
14 | necessary to let C functions manipulate Perl values and creates the glue |
15 | necessary to let Perl access those functions. The compiler uses typemaps to |
16 | determine how to map C function parameters and variables to Perl values. |
17 | |
18 | The compiler will search for typemap files called I<typemap>. It will use |
19 | the following search path to find default typemaps, with the rightmost |
20 | typemap taking precedence. |
21 | |
22 | ../../../typemap:../../typemap:../typemap:typemap |
23 | |
24 | =head1 OPTIONS |
25 | |
26 | =over 5 |
27 | |
28 | =item B<-C++> |
29 | |
30 | Adds ``extern "C"'' to the C code. |
31 | |
32 | |
33 | =item B<-except> |
34 | |
35 | Adds exception handling stubs to the C code. |
36 | |
37 | =item B<-typemap typemap> |
38 | |
39 | Indicates that a user-supplied typemap should take precedence over the |
40 | default typemaps. This option may be used multiple times, with the last |
41 | typemap having the highest precedence. |
42 | |
8e07c86e |
43 | =item B<-v> |
44 | |
45 | Prints the I<xsubpp> version number to standard output, then exits. |
46 | |
8fc38fda |
47 | =item B<-prototypes> |
382b8d97 |
48 | |
8fc38fda |
49 | By default I<xsubpp> will not automatically generate prototype code for |
50 | all xsubs. This flag will enable prototypes. |
51 | |
52 | =item B<-noversioncheck> |
53 | |
54 | Disables the run time test that determines if the object file (derived |
55 | from the C<.xs> file) and the C<.pm> files have the same version |
56 | number. |
382b8d97 |
57 | |
6f1abe2b |
58 | =item B<-nolinenumbers> |
59 | |
60 | Prevents the inclusion of `#line' directives in the output. |
