CNC_RDHNDINTRPT | POSITION

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

Specify the data type.

Specify the pointer to the number of data to be read.
This function returns the number of data which was read actually.

Specify the pointer to the array of ODBHND structure to store the handle interruption values.
The number of array must be equal to "*data_num". The ODBHND structure is as follows.

typedef struct odbhnd {
    POSELM  input;  /* input unit */
    POSELM  output; /* output unit */
} ODBHND ;

input

The POSELM structure for the handle interruption value of input unit

output

The POSELM structure for the handle interruption value of output unit

And the POSELM structure is as follows.

typedef struct poselm {
    long    data;   /* handle interruption value */
    short   dec;    /* place of decimal point of handle interruption value */
    short   unit;   /* unit of handle interruption value */
    short   disp;   /* status of display */
    char    name;   /* axis name */
    char    suff;   /* subscript of axis name */
} POSELM;
