Hi, after some more investigation the easiest way to get Win32WideString from external module is to pass it as a parameter, like in:
^self ffiCall: #( void myFunction ( Win32WideString aWin32WideString ) ) and the external module can access it directly to do r/w. There are other possibilities as well - like adapting the method Win32WideString>>#fromHandle: to translate from ExternalData to Win32WideString, creating new ExternalType, or even creating a new FFIWin32WideString. I wonder what would be the best approach :-) Best wishes, Tomaz -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
