How can I check if a file exists in CVI Real Time?

It would also be nice if the help file designated whether functions were supported in real time or now.

I tried this:

    if(GetFileAttrs (DataFileName,NULL,NULL,NULL,NULL) == -1)

You can check if a file exists in CVI Real-Time using GetFileInfo function.

The CVI help provides a list of functions available on CVI Real-Time here: CVI Real-Time Functions

Excellent.  Now how to I tell if the file is currently open (fopen) so I know whether to close it or not?

Thanks!

It looks like I just do this:  if (filePointer) fclose(filePointer);
