Creates the structure of two structures
#include <WinAPIMisc.au3>
_WinAPI_UnionStruct ( $tStruct1, $tStruct2 [, $sStruct = ''] )
| $tStruct1 | The structure that contains the first source data. |
| $tStruct2 | The structure that contains the second source data. |
| $sStruct | [optional] The string representing the final structure (same as for the DllStructCreate() function). |
| Success: | "byte[n]" structure that contains the union data of the $tStruct1 and $tStruct2. |
| Failure: | Sets the @error flag to non-zero. |
Important, you have to take into account the alignments of the structures. For example, "byte" & "dword" is
not equivalent to "byte;dword", but equivalent to "align 1;byte;dword".
