Re: opendir() - THE ANSWER

The example I gave is a CALL from a command line - if one uses it, even 
against Scott's sage counsel (and I do  agree that there are risks) - 
then build a prototype as you need - the order of the parameters is not 
material, other than it needs to reflect the order as given in the 
documentation for the QShell function - I think they could all be 
character parameters - in fact, they have to be - think of the MAIN in C 
- argc and argv - the former being how many arguments and the latter 
being an array of pointers to chars.

No return value, unless it'd be an integer - hmmm - interesting - that 
would not be surprising.

There's no overhead here - it is a simple call to a program in a library.

But YMMV - widely perhaps
