    ICM_QUERYPROFILE Determines whether the profile is already installed in the system.
    ICM_SETDEFAULTPROFILE Makes the profile first among equals.
    ICM_REGISTERICMATCHER Registers a CMM in the system. The pszFileName parameter points to a fully qualified path for the CMM DLL. The lpszCMID parameter points to a DWORD identifying the CMM.
    ICM_UNREGISTERICMATCHER Unregisters the CMM from the system. The lpszCMID parameter points to a DWORD identifying the CMM.
    ICM_QUERYMATCH Determines whether a profile exists based on the DEVMODE structure pointed to by the pszFileName parameter.
