Ok, there is one correction ot the program I sent in my previous mail...
The parent directory needs to be both writable and executable.

Change the following lines:
                ...
                printf(" - checking parent directory %s\n",dir);
                if ( access(dir,W_OK|X_OK) == -1 ) ok = 0;
                if ( !ok )
                    printf(" - parent dir does not exist or is not writable and 
executable\n");
                ...
--le
