I need to write a program for linux in c++ that pipes data to another application, basically I want to be able to do the following on the command line:
The other program does not support reading files directly but it does have an --stdin parameter. I just need to know how I can send data to the other side of a pipe like above from within a c++ app.
Does myapp's stdout automatically get piped to the other programs stdin?
What you are referring to are command-line pipes, which are defined as forwarding stdout of the former program to the stdin of the latter. Means, write to stdout / cout in your application, and you are fine.
Every good solution is obvious once you've found it.
