I was playing with TCP functions and noticed that if it failed it only gave the WSA error number without any additional info.
So I made this function that returns extended info about a WSA error number in an array.
Just input the WSA error code and get an array such as :
[0] error number
[1] error name
[2] error title
[3] error description

If the input isn't a number, return 0 and set error to 1
If the input couldn't be found, return 0 and set error to 2

Here's the function :

Func WSAerrorToText($error)

    If NOT IsNumber($error) Then Return SetError(2, 0, 0)

    Local $return[4] = [$error, "Unknown", "Unknown", "Unknown"]

    Switch $error

Why ? It would return an empty array.

I know, but it would not hurt. When coding, and not properly handling errors, returning the empty array, would save the script from a possible cash, as a array is expected.
You could even initialize the array as [$error, "not found", "not found", "not found"]. Is just a nice touch.

Thanks for sharing :)
