NAME
    CloseDevice -- conclude access to a device

SYNOPSIS
    CloseDevice(iORequest)
                A1

    void CloseDevice(struct IORequest *);

FUNCTION
    This function informs the device that access to a device/unit
    previously opened has been concluded.  The device may perform
    certain house-cleaning operations.

    The user must ensure that all outstanding IORequests have been
    returned before closing the device.  The AbortIO function can kill
    any stragglers.

    After a close, the I/O request structure is free to be reused.
    Starting with V36 exec it is safe to CloseDevice() with an
    IORequest that is either cleared to zeros, or failed to
    open.

INPUTS
    iORequest - pointer to an I/O request structure

SEE ALSO
    OpenDevice
