Write digital snapshot value to PI

You can use floating point numbers to write long pt = 177; int rs; double v_d = 0; rs = pisn_putsnapshotx (pt, & v_d, NULL, NULL ); 0.0 ~ The number between 1.0, as 1; 1.0 ~ The number between 2.0 and 2. Similarly, you can use the integer number to write long pt = 177; int rs; long v_ I = 0; rs = pisn_putsnapshotx (pt, NULL, & v_ I, NULL, NULL); if the written value is Not in the digitalset corresponding to this point, data cannot be written. The error value-10702 [-10702] STATE Not Found is returned.
