How do I figure out if the fd (specifically, stdin=0) is open?
apparently it is closed when the application is run by nohup.
the only thing I could figure out so far is fstat: when 0 is open,
st_mode is 8592, when it is closed it is 8630...
PS. Sorry about asking here, this is the most knowlegeable unix forum I know...
