{{DISPLAYTITLE:MM_MCINOTIFY}}
This message notifies an application when a device completes the action indicated by a media message or when an error occurs.

==Syntax==
<PRE>
MsgParam1
USHORT usNotifycode;    /* Notification code. */
USHORT usUserParameter; /* User parameter. */

MsgParam2
USHORT usDeviceID;      /* Device ID. */
USHORT usMessage;       /* Message ID. */
</PRE>

==Parameters==
;''usNotifycode'' ([[USHORT]]) - input
:Specifies the following notification message code:
:* '''MCI_NOTIFY_SUCCESSFUL''' The command was completed successfully.
:* '''MCI_NOTIFY_SUPERSEDED''' Another notification request (same type of command) was received.
:* '''MCI_NOTIFY_ABORTED''' The command was interrupted and is unable to be completed. For example, the first command was a PLAY with notify, and the second command was STOP with or without notify.
:Any other value indicates an error, and that value is the error number. [[mciGetErrorString]] can be used to convert the number into a textual description of the error.

;''usUserParameter'' ([[USHORT]]) - input
:Contains the user parameter specified on [[mciSendCommand]] or [[mciSendString]] for this command.

;''usDeviceID'' ([[USHORT]]) - input
:The media control interface device ID included in the notification.

;''usMessage'' ([[USHORT]]) - input
:Specifies the message ID which generated the notification.

==Returns==
;''rc'' ([[BOOL]]) - return: Success indicator.
::TRUE: Successful completion.
::FALSE: Error occurred. (Note: The return value is typically ignored for this posted message.)

==Remarks==
This message is posted to the window specified in the ''hwndCallback'' field of the parameter data structure used with the command (e.g., MCI_PLAY, MCI_RECORD, etc.).

==Default Processing==
The default window procedure does not expect to receive this message and therefore takes no action on it, other than to set ''rc'' to the default value of FALSE.
