coprocess questions (manpage doesn't seem clear)

[Linda Walsh]

I was looking @ coprocess section in the manpage where it says that:

 NAME must not be supplied if command is a simple command.
 For the coproc:
   FH1(stdout) is put in NAME[0]
   FH0(stdin)  is put in NAME[1]
   PID is put in NAME_PID

Questions (Seems like these should be in manpage, in this section, or
has this already been revised?):

 1) If Name isn't supplied, where does it put the handles & Pid?

 2) Where does it put FH2 (stderr)?
