pipe in read and write mode

[Raphael Bauduin]

Hi!

I want to pipe the standard input of my script to a command. I use popen, 
and it's fine. However, I want to take the standard output of the command 
and put it in a variable. I can't open the pipe in read and write mode. I 
made it work by redirecting the output of the pipe to a file, and reading 
this file. I would prefer not to write it to a temporary file, as the text 
piped is somewhat sensitive (I use the script to encrypt it, so it would be 
better not to write it to a file ;-)


thanks.
