This section describes the server control call that lets you send messages to
users.
SCSendMessage
The following function calls SCSendMessage to send a message to the users
specified in the array pointed to by DiscArrayPtr.
Note This call is not supported by Macintosh File Sharing.
FUNCTION MySCSendMessage (DiscArrayPtr: LongIntPtr;
ArrayCount: Integer;
Flags: Integer;
MessagePtr: StringPtr): OSErr;
VAR
scPB: SCParamBlockRec;
BEGIN
scPB.disconnectPB.scDiscArrayPtr := DiscArrayPtr;
scPB.disconnectPB.scArrayCount := ArrayCount;
scPB.disconnectPB.scCode := SCSendMessage;
scPB.disconnectPB.scFlags := Flags;
scPB.disconnectPB.scMessagePtr := MessagePtr;
MySCSendMessage := SyncServerDispatch(@scPB);
END;
The following procedure sends a message to all connected users. Before using
this routine, you must initialize gCurMaxSession by using the SCGetSetupInfo
call.
PROCEDURE SendMessageToAll;
{ This routine depends on gCurMaxSessions being }
{ initialized with SCGetSetupInfo. }

err: OSErr;
ArrayPosPtr: LongIntPtr;
Position: LongInt;
