I'm posting this for a friend. Please reply to him, not me.

-----------------------------------------------------------------------
I would like to extend Mathematica by installing some C procedures.
According to the on-line documentation, this should be easy to do
using the interface procedures defined in the file mathlink.c  Unfortunately,
mathlink.h is empty and I have apparently not added the correct function
prototypes to make mathlink.c work.  Would anyone who has been successful
with mathlink please pass along some pointers (sorry the pun was intended).

I have also tried to communicate with Mathematica using pipes.  I've had
some success; however, when I send the string
  "ResetMedium[\"stdout\",PageWidth->Infinity]; $PrePrint=FullForm"
I get a message saying the Mathematica cannot parse the expression.
Any suggestions?
