7 back
8
10 version 2.08
11
13 In your C code:
14
15 void
16 string_pointer_argument(const char **string)
17 {
18 ...
19 }
20 const char **
21 string_pointer_return(void)
22 {
23 ...
24 }
25
26 In your Platypus::FFI code:
27
28 use FFI::Platypus 2.00;
29
30 my $ffi = FFI::Platypus->new( api => 2 );
31 $ffi->load_custom_type('::StringPointer' => 'string_pointer');
32
33 $ffi->attach(string_pointer_argument => ['string_pointer'] => 'void');
34 $ffi->attach(string_pointer_return => [] => 'string_pointer');
35
36 my $string = "foo";
37
38 string_pointer_argument(\$string); # $string may be modified
39
40 $ref = string_pointer_return();
41
42 print $$ref; # print the string pointed to by $ref
43
45 NOTE: As of version 0.61, this custom type is now deprecated since
46 pointers to strings are supported in the FFI::Platypus directly without
47 custom types.
48
49 This module provides a FFI::Platypus custom type for pointers to
50 strings.
