Specify the slave number to read.

Pointer to the IODBPRFADR structure including the address allocation. The IODBPRFADR structure is as follows.

typedef struct {
    unsigned char  di_size ;
    char           di_type ;
    unsigned short di_addr ;
    short          reserve1;
    unsigned char  do_size ;
    char           do_type ;
    unsigned short do_addr ;
    short          reserve2;
    unsigned char  dgn_size;
    char           dgn_type;
    unsigned short dgn_addr;
} IODBPRFADR ;
