NAME
    FindConfigDev - find a matching ConfigDev entry

SYNOPSIS
    configDev = FindConfigDev( oldConfigDev, manufacturer, product )
    D0                         A0            D0            D1

FUNCTION
    This routine searches the list of existing ConfigDev
    structures in the system and looks for one that has
    the specified manufacturer and product codes.

    If the oldConfigDev is NULL the the search is from the
    start of the list of configuration devices.  If it is
    not null then it searches from the first configuration
    device entry AFTER oldConfigDev.

    A code of -1 is treated as a wildcard -- e.g. it matches
    any manufacturer (or product)

INPUTS
    oldConfigDev - a valid ConfigDev structure, or NULL to start
            from the start of the list.
    manufacturer - the manufacturer code being searched for, or
            -1 to ignore manufacturer numbers.
    product - the product code being searched for, or -1 to
            ignore product numbers.

RESULTS
    configDev - the next ConfigDev entry that matches the
            manufacturer and product codes, or NULL if there
            are no more matches.

EXCEPTIONS

EXAMPLES
    /* to find all configdevs of the proper type */
    struct ConfigDev *cd = NULL;

    while( cd = FindConfigDev( cd, MANUFACTURER, PRODUCT ) ) {
            /* do something with the returned ConfigDev */
    }
