Re: [Swig-devel] handling binary std::strings in C#

[David P. <dpi...@me...>]

Whoops, my last message included unnecessary char* typemaps. Here's the
string stuff alone. Again, it's not tested yet and it can only do what
you want for returning strings from C++ to C#.

%include std_string.i

%insert(runtime) %{
#include <ole2.h>
%}

namespace std {

// string
%typemap(ctype, out=3D"/*ANSI*/BSTR") string, const string & "char *"
%typemap(imtype,
outattributes=3D"[return:MarshalAs(UnmanagedType.AnsiBStr)]",
inattributes=3D"[MarshalAs(UnmanagedType.LPStr)]") string, const string =
&
"string"
%typemap(out) string, const string& %{ $result =3D
SysAllocStringByteLen($1.c_str(), $1.size()); %}
%typemap(out) const string& %{ $result =3D
SysAllocStringByteLen($1->c_str(), $1->size()); %}

}
