Could anybody show me an example C/C++ function returning just a string, please without passing any parameters!
In the help file it passes strings, too.
I need that to be sure that I understand it right.
Couldn't I just return the pointer to a global string?

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

char *returnString(){
char *strRet=new char[20];
strcpy(strRet, "Hello world");
return strRet;
}

int main(){
char *str=returnString();
printf("%s", str);
delete str;
}

No, for DBPro TPCs, anyway, I already know now how it works.
