Hello,

I have some techical difficulties converting uni-processor version of my "C"
program (it's a planner) to a parallel version using PVM.

The problem is I'm trying to make children processes share a set of file pointers
with the parent process (the file pointers are opened by parent process).
I'm wondering if there is any way of passing file pointers from a parent process
to other children processes. 
The children processes of the planner need to perform their own output operations
during some computations because the output operations themselves need to be 
distributed.

Actaully, I'm expecting a way of handling this to exist in PVM because the
distributed processing is supposed to work on NFS, which make the directory 
structure transparent to users across the network.


I'm also looking for a way of passing pointer data types to other processes
in PVM.

Thanks a lot for your attentions.
