help with execve

   I am trying to run a process within a program by using 'execve'.  More
   specifically, I want to execute the 'login' command so I can log on to
   another machine into my other account.  I am having trouble getting it
   to accept my password, though.  First of all, it doesn't seem to
   accept it from stdin, because I first tried to pipe it in.  Also, it
   seems to prompt for the password over stderr.  Is there any way to
   send input to this process?  Am I just going to have to give up and do
   it manually??  Should I be using something other than execve???

   Help would be greatly appreciated...thanks in advance...if I've said 
   something really stupid, no flames, please (I've RTFMed and it hasn't
   helped)...

I can't imagine what you're trying to do.
Anyway, the password is read from the terminal with getpass(3), and if
you had RTFMed a little better you would know that it reads the password
from /dev/tty, not stdin.
