Are you using relative file paths?

The CWD of the task executing 'Process' may not be what
you think...

I have a genSub I've setup to run test code on my IOC, and I'm getting
errors when I try to read the test set data files. This is an RTEMS 4.7.1 based
IOC accessing an NFS mounted filesystem.     I'm able to read the same
files from a genSub Init function, but not from the Process function.
I can also read these files if I initiate the test from the Cexp shell on the RTEMS
console.

Is there something about how the Process functions are called that would
preclude file I/O?

Thanks!
