Sorry, but after I sent the email above I realized that I was editing a file in the wrong folder. Free Pascal doesn't work with "var" on the line below: var str : Pchar;This is what works on FPC 2.6.4: function ps5000aGetUnitInfo (handle : smallInt; Str : Pchar; stringLength : smallInt; var requiredSize : smallInt; info : integer ) : integer; {$IFDEF WIN32} stdcall; external 'ps5000a.dll';{$ENDIF}
It will work in both FPC and Delphi if you pass @MyReturnStr[1], provided that the length of MyReturnStr is sufficiently large. When dealing with addresses to strings/arrays, always explicitly specify the first element you want to use rather than the entire string/array. That will always work regardless of the string or array type (static/dynamic/open/... array, ansi/short/wide/..., and even pchar).
