List Hi,
I still I can read my IFS file. I get the error 3440 (ENOTSUP 3440 Operation is
not supported. EOPNOTSUPP 3440 Operation is not supported.).
I am attaching a list of the program. I run the program in debug where I
spotted the error. The path is passed as parameter: (/DIR/SUBDIR/FILE).
The error occurs in line 123 attempting to read the file, nbytesread has a
value of -1. DspError shows the error.
Any help is welcomed.
