NFS

[Kirspel, Kevin]

The reason I was so confused was that my version of rtems is 4.6.99.4 which
does not have the c/src/nfsclient directory.  I had read that README file
from another website but could never find any source code for the
rpcUdpInit() and nfsInit() functions.  I think I will upgrade now.

You don't have to do anything. The libraries should be part of librtemscpu.a

1) You shouldn't have to start the portmapper. That is only needed if 
you run a
RPC server on your rtems box.

2) - setup and initialize networking
- call 'rpcUdpInit()' [ generic multi-threaded RPC-over-UDP client ]
- nfsInit(0,0) [ initializes NFS client on top of RPC-UDP ]
- nfsMount("<server-dotIP-or-name>","<server-export>","<mountpoint>")
[ nfsMount creates the mount point for you if
it doesn't exist yet.

3) If you bother to RTM [ <rtems-src-dir>/README ] you'll find a more
detailed description.
