Data Formatters - XCode 2.0

I am trying to make a Data formatter plugin for one of our data types. It is a string class that we use, similar to a C++ string.

The plugin is being called, but is apparently not working correctly.

As an example I am also trying to do it using a C++ string. I KNOW THAT I CAN SIMPLY TYPE {$VAR.c_str()}:s IN THE SUMMARY FIELD FOR A C+ + STRING!!! Please don't tell me to try this.

Our string type also has a c_str() method, but is returning unicode and can't be displayed properly this way.

So, after all that, here is what I am trying to do, assuming I am using a C++ string

//==========PLIST SNIPPET==========
    <key>string</key>
    <dict>
        <key>SummaryString</key>
        <string>{(char *)string_summary($VAR, $ID)}:s</string>
    </dict>
//==========PLIST SNIPPET==========

//==========CODE SNIPPET==========

char* string_summary(const string &str, int identifier)
{
char *result = NULL;
if ( NULL != _pbxgdb_plugin_functions )
{
// if I replace str in the formatter with s1, this string IS displayed
std::string s1 = "This is a c++ string";
result = _pbxgdb_plugin_functions->message(identifier, "<% s>", str.c_str());
}
return result;
}


//==========CODE SNIPPET==========

When I run in the debugger, all I get in the summary field is "out of scope", but the variable name is not grayed. If I replace str with s1, then the string "This is a C++ string" will always be displayed.

Am I totally missing the mark here? Why doesn't Apple provide an example of how to do this?

Any guidance would be appreciated.
