HRESULTCyclomyCoInstaller( IN DI_FUNCTION InstallFunction, IN HDEVINFO DeviceInfoSet, IN PSP_DEVINFO_DATA DeviceInfoData OPTIONAL, IN OUT PCOINSTALLER_CONTEXT_DATA Context)/*++
Routine Description:
This routine is a Co-Installer for the Cyclom-Y device.
Arguments:
InstallFunction - Specifies the device installer function code indicating the action being performed.
DeviceInfoSet - Supplies a handle to the device information set being acted upon by this install action.
DeviceInfoData - Optionally, supplies the address of a device information element being acted upon by this install action.
Context - Points to a coinstaller-specific context structure for this installation request.
Return Value:
If this function successfully completed the requested action, the return value is NO_ERROR.
If an error occurred while attempting to perform the requested action, a Win32 error code is returned.

Routine Description:
Given a DI_FUNCTION value, returns a text representation.
