Hi group,
i got a problem regarding anonymous pipes.

i want to invoke a process on which i do not have any control.
(means i don't have it's source code in my hand)(means i have an exe in
hand).
what i want to do is invoke this as child process.
and i should be able to send it some strings.

i am able to invoke it using CreateProcess
and also able to redirect it's stdout to the pipes write end and after
that reading it from the read end in parent process.

but is it possible in stdin's case?

what i was thinking is something like this
first create two pipes in parent process.
one for reading and another for writing.(inheritable)
then invoke the process using CreateProcess()
and read it.

so can anybody please explain me this scenario in greater detail.

It sounds like you already know how to do it. Concerning the read and write
ends of a pipe, redirecting an input stream is the opposite of redirecting
an output stream. You'll need two threads, one to write to the child
process's input and another to read its output.
