I have a project that I'm working on that involves creating a shared
library.  I understand how to create one, but I don't know the
limitations on using one.  (I'm writing it in Lattice C 5.02.)
 
In particular:  can I use dos functions?  I ask this because the XPR
specs use callbacks for dos functions.  I understand why XPR would need
callbacks for doing Serial I/O, but not why it would need callbacks for
file i/o.
 
Also, if I do a FindTask(0) during the Opening of my library (ie: when
another program does an OpenLibrary) will I get a pointer to the tcb of
the calling task?  Could I use this pointer to set up a separate data
structure for each calling task?
 
Thanks in advance.
