CNC_SDTREADSMPL | MOTOR

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

Specify the pointer to the variable in which the status of data reading is stored.

When this argument(stat) is "0", execute the cnc_sdtendsmpl.

Specify the number of sampling data which you want to read. (Specify the value of eight or more.)
Reading process is executed every 8WORD unit. So, specify the multiple of eight as much as possible for this value.

Specify the pointer to the array of ODBSD structure to store the sampling data. The sampling data is acquired in order of channel which was set by cnc_sdtsetchnl function.

The structure of ODBSD is as follows.

typedef struct odbsd {
    unsigned short  *chadata;   /* Pointer to sampling data  */
    long            *count;     /* Pointer to reading number */
} ODBSD;

Prepare the buffer area for the sampling data and the area for the number of actually read data. And the each pointer is set to ODBSD structure.
Prepare ODBSD structures of the same number of channels as array.
And specify the top pointer of this array to this argument. After the function is executed normally, the actual number of reading data in each channel is acquired in *count.
