Description
The function clears the buffer of dpCopy(). If the source data point is copied several times, then the information is read only once. The buffer is reloaded, if you copy another source data point. If you change the source data point of the same data point type during copying, then you have to clear the buffer with the function dpCopyBufferClear(). Otherwise the old information would be copied.
Exampl e
Creating two data points. Change the source data point ExampleDP_Arg1 during the delay (for example, insert a config). The data point test2Copy accept the new config only after clearing the buffer with
dpCopyBufferClear().
main()
{
int x,y;
dpCopy("System1:ExampleDP_Arg1", "test3Copy", x);
DebugN(x);
delay(20);// insert config
dpCopyBufferClear(); //clearing buffer
dpCopy("System1:ExampleDP_Arg1", "test2Copy", y);
// new config accept
DebugN(y);
