Hey there.
I was battling with timers and invalid handle errors the last days until i found my problem.
I had this stock

View code

PHP Code:

stock SafeCloseHandle(Handle:rHandle)
{
    if(rHandle != INVALID_HANDLE)
    {
        CloseHandle(rHandle);
        rHandle = INVALID_HANDLE;
    }
} 


After debugging my problem was solved with this code.

PHP Code:

stock SafeCloseHandle(&Handle:rHandle)
{
    if(rHandle != INVALID_HANDLE)
    {
        CloseHandle(rHandle);
        rHandle = INVALID_HANDLE;
    }
} 


I did not completely read the documentation yet, but i could not find it in the sites it supposed to be.
Now my question is: What this character is doing in that case and why do i need it?

Yours sincerely

I'm not 100% sure about Pawn here but I guess it is the reference operator:

This means you don't pass a copy of the Object to the function but you pass a reference to the original Object to the function so you can operate on the original Object rather than on a copy.

Yep, that makes sense.
Thank you very much.

Yes, it's the pass by reference operator.

CloseHandle in your statement worked fine, the problem was with

PHP Code:

rHandle = INVALID_HANDLE; 


If you don't have the & operator, this doesn't actually do anything, as the calling function still has the old value for the Handle.
