delphi – How to convert a null terminated string to string? – Stack Overflow

An old trick that I tend to forget: [WayBack] delphi – How to convert a null terminated string to string? – Stack Overflow:

You can assign a null-terminated PChar directly to a String:

function GetFileName(DiskName: TFileNameIO): string;
begin
 Result := PChar(@DiskName);
end;

It can work even on string literals and constants, where you can leave out the @, like in:

var
  S: string;
begin
  S := PChar(FastMM4Messages.LogFileExtension;

Probably time to update the unit I mention in ISO 8601 Date, Time and DateTime in Delphi (was: Simple example to show DateTime.Now in ISO 8601 format on ideone.com | Online C# Compiler & Debugging Tool).
