Viewing Detailed Call Information

You can see detailed call information for every captured API call in NI Spy using the Properties dialog box. The Properties dialog box includes one to four pages of detailed information on the captured call. All captured calls have a General page, most captured calls have Input and Output pages, and some captured calls have a Buffer page. The General page displays information about the application that made the API call and time statistics for the API call. The Input page displays the API call's input parameters. The Output page displays the API call's return parameters upon call completion. The Buffer page is present only for calls that involve the transfer of a buffer of data; this page displays the contents of the data buffer.

For help on the characteristics of the General, Input, Output, and Buffer pages, look at the context-sensitive help in the NI Spy application by using the question mark button on the title bar of the Properties dialog box .

To see the Properties of a specific call, double-click on the call in the capture window, select View»Properties, or right-click on the call and select Properties.

Note  If no input, output, or buffer information exists for a particular call, that page is not displayed in that call's Properties dialog box.
