Question

I loaded up some old code from Delphi Magazine and when I compile it inside Delphi 2010 I get an E2010 Incompatible types: ‘AnsiChar’ and ‘Char’.

How do I resolve this error?

pAddr := inet_ntoa(AddrIn.sin_addr);

pAddr defined as PChar
inet_ntoa is a function that returns PAnsiChar

Answer 1

Use an AnsiString and a String to safely perform the necessary casts.

MyAnsiString := AnsiString(inet_ntoa(AddrIn.sin_addr));
MyString := String(MyAnsiString);
pAddr := PChar(MyString);
