## -remarks

When the <b>Pull</b> method is called, data is requested from the provider of the pipe. The caller must provide a buffer that will hold at least the number of double integers specified in the <i>cRequest</i> parameter. The proxy will unmarshal the data into the provided buffer and set the number of double integers actually provided in <i>pcReturned</i>. The <i>pcReturned</i> parameter can be less than or equal to <i>cRequest</i>, but it will never be greater. When <i>pcReturned</i> is 0, it indicates that there is no more data.
