Can a function return more than one result?

Is it possible to make a function that when called will return more than one result?

This is what I am trying to do, but I don't see how to return two results:

Func RunCmd($cmd)
  [....]
  Return $stdout, $stderr
EndFunc

RunCmd("dir C:\")
MsgBox (0,"Results", "Stdout: " & $stdout & @CRLF & "Stderr: " & $stderr)

Hi Javik,

no, there is no such possibility.

But you could pass variables and alter them using the "ByRef" statement.

:huh2:

If you look at the example for StringReplace() in help file, the modified string is returned, and the number of replacements is returned in @Extended.

For your own function you can use the SetError() function.

Javik,

Of course it is possible! :alien:

Return an array with the elements set to the values you want to return: :huh2:

#include <Array.au3>

$iA = 2
$iB = 3

$aRet = _Double($iA, $iB)

_ArrayDisplay($aRet)

Func _Double($v1, $v2)

    Local $aRet[2]

    $aRet[0] = $v1 * 2
    $aRet[1] = $v2 * 2

    Return $aRet

EndFunc

Or use ByRef as Hannes123 suggested. ;)

You can return values from a function by:

The Return keyword. The return value can be a single variable or an array

The macros @error and @extended.: Use function SetError to set this macros

ByRef parameters: If you pass parameters to a function using ByRef you can change them in your function.

A lot more ...

And the option that seems to be omitted:

Your function can use recursion (advanced) or just write the results / return values in a file!
