Passing errors through pipes.

[Jody Winston]

If I have program a piping information to program b.  ie.

a | b

If it is possible, how would one pass a read error from a to b
only using pipes (signals can't be used, sockets or streams can't
be used, and the error can't be imbeded in the data stream).
