Delphi dll function import under QT

[Gep]

Function parameter is the problem:

function GetAdminSID: String;

function GetAdminSID: String;

To copy to clipboard, switch view to plain text mode 

becouse I changed:

function GetAdminSID: PChar;

function GetAdminSID: PChar;

To copy to clipboard, switch view to plain text mode 

Everything works fine.

but unfortunately, this DLL is already in use. So I would not change. This version should I use:

function GetAdminSID: String;

function GetAdminSID: String;

To copy to clipboard, switch view to plain text mode 

Is idea someones of the declaration I how to change?

extern "C" { typedef char*(__stdcall * PGetAdminSID)(); }

extern "C" { typedef char*(__stdcall * PGetAdminSID)(); }

To copy to clipboard, switch view to plain text mode 

Thanks!
