Naming the Capture File
The following example uses the capFileSetCaptureFileG_63ME macro to specify an alternate filename (MYCAP.AVI) for the capture file and the capFileAlloc12LYBSY macro to preallocate a file of 5 MB.
char szCaptureFile[] = MYCAP.AVI ;
capFileSetCaptureFile( hWndC, szCaptureFile);
capFileAlloc( hWndC, (1024L * 1024L * 5));
