But with using "*mem\s = *str\s", PB made the copy and create a new buffer . Or I'm wrong...?
No, you're quite right.
PB's way of handling the '@' operator for strings can be a bit confusing at times.
As you can se from the different answers you're getting
So my procedure is quite good, excepted the null pointer case ?!
Code: Select all
Procedure.l V__Constructor_String(*param = #Null)
Protected *str.String, *mem.String
*mem = Vector__Allocate(SizeOf(String))
If *param
*str = @*param
*mem\s = *str\s
Else
*mem\s = ""
EndIf
ProcedureReturn *mem
EndProcedure
So the problem came from another place ?!

Yes i think the procedure is just fine, so there might be another problem somewhere in the code. One thing i wonder though, how is the result from the string constructor procedure handled?

The return is used has a pointer of a STRING structure :

That should be OK.
Sorry, i'm afraid you have to do some more bug hunting
Are you using any threads or are the code compiled into a DLL?

Yeah, I'm using Threads, and the only way the program bug is in the Threaded functions. I hope that PB have no more bug with threads and strings.
PS : I'have checked "Thread safe" in compiler options.
