NAME

7       back

VERSION

10       version 1.58
11

SYNOPSIS

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;
29
30        my $ffi = FFI::Platypus->new( api => 1 );
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

DESCRIPTION

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.
