#include <WinAPISysWin.au3>
_WinAPI_BroadcastSystemMessage ( $iMsg [, $wParam = 0 [, $lParam = 0 [, $iFlags = 0 [, $iRecipients = 0]]]] )
| $iMsg | The message to be sent. |

| $lParam | [optional] The message-specific information. |
| $iFlags | [optional] The broadcast option. This parameter can be one or more of the following values: $BSF_ALLOWSFW $BSF_FLUSHDISK $BSF_FORCEIFHUNG $BSF_IGNORECURRENTTASK $BSF_NOHANG $BSF_NOTIMEOUTIFNOTHUNG $BSF_POSTMESSAGE $BSF_QUERY $BSF_SENDNOTIFYMESSAGE |

| Success: | >0 or 0 (see below), @extended flag receives a combination of $BSM_* values identifying which recipients actually received the message. |
| Failure: | (-1), call _WinAPI_GetLastError() to get extended error information. |
If the $iFlags parameter is $BSF_QUERY and at least one recipient returned BROADCAST_QUERY_DENY to the corresponding message, the return value is 0.
The system only does marshalling for system messages (those in the range 0 to (WM_USER-1)).
To send other messages (those >= WM_USER) to another process, you must do custom marshalling.
