Re: Reading From an NFS

Hello Hoss,

When I open the file it returns a handle gHandle =
open(%trim(fnwithdir): O_RDONLY: S_IRWXU + S_IRWXG + S_IRWXO);

This isn't the problem, but... just a note: the S_xxx flags are not going to be used in the above example. The S_xxx flags are only used if you specify O_CREAT. So the following code would be identical to what you have:

gHandle = open(%trim(fnwithdir): O_RDONLY);

When I read the file gBytes is 0 Zero. gBytes = read(gHandle:
gDataPtr: gDataPtrSize);

What are gDataPtr and gDataPtrSize? How are they defined? What are they set to?

Most commonly, an RPG program calling the read() API would look more like this:

gBytes = read(gHandle: %addr(someVar): %size(someVar));

For certain, you can provide your own pointer and your own size variable instead of using a preexisting RPG variable -- but please make sure you specify valid values for them... If you set them wrong, you could very well have the issue you're describing (that it can't read the data)

However, aside from that, I don't see anything wrong. I tried your code (filling in the blanks as best I could) and was able to successfully read a file from my NFS server. Granted, my NFS server is running FreeBSD rather than Windows, but I don't see why that would matter...
