How can I return a string in a Purebasic dll as a pchar value to Delphi?

Any suggestions are welcome.

have your dll allocate the string data to a memory address, then pass this address to your delphi application. if delphi reads normal ascii strings then it'll work. if not, drop delphi, it's crap.

From what I read online pchar is basically a pointer to a bit of memory allocated for string use. Try adding an @ in front of the variable when you pass it to your procedure and see if it works.

Code: Select all

procedure.. ( param1, @string.s )

If your dll declares a string as geing global and returns that, then I see no reason why this should not work.

srod has a good point. Make sure that your string isn't a local variable that pops after your function passes the pointer.
