MCISPY (located in \TOOLKIT\SAMPLES\MM\MCISPY) monitors media control interface messages that are exchanged between applications and the OS/2 multimedia subsystem.

In addition to teaching you about multimedia messages, MCISPY also serves as a powerful debugging aid.

The MCISPY sample must be manually set up. To do so, follow these steps:

• Copy the MDM.DLL file located in the \MMOS2\DLL subdirectory to the \TOOLKIT\DLL subdirectory.

• Use the DLLRNAME tool (available with C Set ++ or VisualAge C++) to rename the copy to MCI.DLL. To do this, type:

  DLLRNAME MDM.DLL MDM=MCI
  

• Create the executable (MCISPY.EXE) and the stub DLL (MDM.DLL) by running the MCISPY makefile.

• Place the stub MDM.DLL, built by the MCISPY makefile, in the LIBPATH so that it is recognized prior to the MDM.DLL file located in the \MMOS2\DLL subdirectory. The source code for the stub MDM.DLL is included in the MCISPY sample.

• Restart your system.

Note: Driver notifications might not be visible in releases prior to OS/2 Warp Version 3. These notifications include all multimedia messages routed through mdmDriverNotify().

Hardware requirements:

• Computer capable of running OS/2 Warp

Software requirements:

• Multimedia support 
  OS/2 Warp

  Note: The files for the samples will be installed when the samples are selected, but Workplace Shell objects will not be created for them if the installed operating system is not OS/2 Warp.
