CNC_WRHISSGNL2 | HISTORY

Specify the library handle. See "Library handle" for details.

Pointer to the IODBSIG2 structure to set the various target signal information for the operation history. The IODBSIG2 structure is as follows.

typedef struct iodbsig2 {
    short      datano;   /* Not used          */
    short      type;     /* Number of signals */
    struct {
        short   ent_no;   /* Registration sequence number   */
        short   sig_no;   /* Registered signal number       */
        char    sig_name; /* Registered signal name         */
        char    mask_pat; /* Signal mask pattern            */
    } data[45];
} IODBSIG2 ;
