returning strings (SOLVED)

[xelanoimis]

Hi!
I want to know if I can create functions that return strings.
If possible, what if the returned string is declared inside the function?
like:
function GetSomeName ()
{
string str = "Alex";
  return str;
}

What about arrays (that are declared inside the function) ?

It's not possible to return strings or arrays that are declared within the function.

To return string data you must declare a string outside a function and then pass it as an out parameter, so that a function can fill it with the data you need:

function GetSomeText(int someParam, string buffer) {

Ã,  Ã,  if (someParam) StrCopy(buffer, "some text");
Ã,  Ã,  else StrCopy(buffer, "nothing");
}

function repeatedly_execute() {


Ã,  Ã,  string buf;Ã,  // declaring a string

Ã,  Ã,  GetSomeText(1, buf); // getting string through that out parameter;

Ã,  Ã,  SetLabelText(GUI, LABEL, buf); // using it;
}

What about arrays (that are declared inside the function) ?

To return an array of data you have to declare a global array and write into it in a server function and then read from in a client function:

int glArray[10];

function GetArrayData(int someParam) {

Ã,  Ã,  if (someParam)
Ã,  Ã,  {
Ã,  Ã,  Ã,  Ã,  glArray[0 ] = 0;
Ã,  Ã,  Ã,  Ã,  glArray[1] = 1;
Ã,  Ã,  Ã,  Ã,  glArray[2] = 2;
Ã,  Ã,  }
}


function on_some_event() {


Ã,  Ã,  GetArrayData(1);

Ã,  Ã,  int x = glArray[0 ];
Ã,  Ã,  int y = glArray[1];
Ã,  Ã,  int z = glArray[2];
}


You can also use GlobalInts as a global array (see SetGlobalInt/GetGlobalInt in the manual). But keep in mind that arrays are not officially supported and that there is no check carried out if you write outside of array bounds:

int array[2];

...

array[10] = 1; // no error generated!!
