Accessing linux,unix and z/os

[jidder]

Okay so say i have three servers or partitions.
one in linux, one in unix and one in z/os.
Would someone be able to explain to me how to access each and whether this can all be done from the same application.

I would include code but i have no idea where to start
I have also googled this but havent been able to find much information.

Thanks

Edit: to add further confusion i will be creating the program on windows
Also the IDE i will be using is codeblocks.

What do you have, 3 servers or 3 partitions on 1 server?

Is the application running on a different compter? Are you talking about file access?

I don't know much about z/os.

Two servers
one is linux
one is unix and z/os
But for the sake of this question just treat them all as separate servers.

Is the application running on a different compter? Are you talking about file access?

Yes to both

I don't know much about z/os.

help on any will be useful :)

Thanks

In a POSIX environment (Unix and Unix-like systems), file sharing would be done with NFS.

The server exports somewhere in the directory tree and the client machine mount's that exported directory.

The actual export config varies between Unixes, but the import is pretty much the same.

There seems to be plenty of hits when I Google "z/os nfs", so I'd expect z/os to support NFS.
