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. }

VAR

err: OSErr;

ArrayPosPtr: LongIntPtr;

Position: LongInt;

scPB: SCParamBlockRec;
