NAME

    FindControllerID

SYNOPSIS

    success = FindControllerID ( devname, selfid )
    D0                           A0       A1
    BOOL FindControllerID ( char *devname, ULONG *selfid );

FUNCTION

    Test open devices until find SelfID error
    ( Of course, this does not work on Commododo "scsi.device" and most
    other implementations. )

INPUTS

    devname Pointer to C string device name for device to be searched.
    selfid  Pointer to a ULONG for storing result. Preload it with a
            value within the expected range of results. (Used to determine
            the board to search.) Note this *MUST* be a ULONG value.

RESULT

    success BOOL, TRUE means value returned in selfid has meaning.
    selfid  Filled with the discovered HostID for the controller card.

NOTES

    Note that the library must NOT have a device open for this test
    to succeed.

BUGS

    This tool searches only the "legal" first 8 SCSI IDs, 0..7, for a
    HFERR_SELFID error return from opening and attempting to issue a
    command to the opened unit. Most controllers do not support this.
