Using a pipe
« on: May 15, 2014, 10:46:33 PM »
Does anyone have a simple example of using a pipe to communicate between a parent and child process?  Thanks!

In assembler, yes:

include \masm32\MasmBasic\MasmBasic.inc      ; download
  Init
  Inkey "Current time is ", Launch$("cmd.exe /C time /T")
  Exit
end start

Seriously: Pipes are a can of worms. For example, to avoid hanging apps, you need to read data in separate threads etc...

To get an idea (and some really good hits), google for SECURITY_ATTRIBUTES HANDLE_FLAG_INHERIT CreatePipe SetHandleInformation CreateProcess WaitForInputIdle CreateThread

These are the standard native applications (from here).
