usage of pipes

usage of pipes

[Jagadeesh Bhaskar P]

Hi,

I created a pipe in a program. Now i want to write through that to
another program. Is it possible? 
Or putting it in other words, can I communicate with a pipe (and not a
named pipe or FIFO), between 2 entirely independent processes?

The other process needs a descriptor for the other end of the pipe. 

AFAIK, there are only two ways to achieve this: either both processes
must have a common ancestor which creates the pipe, or the processes
must communicate via a Unix-domain socket so that the creator can send
the descriptor using sendmsg() with an SCM_RIGHTS message.
