Subject: Re: Problem with popen on windows

Simon, this worked on my machine also --excellent!

---Question / Request:
I tried stripping out the GUI stuff so that I could implement this
'solution' into my current needs (to no avail)

I would like to use this as a replacement to popen(), could you help
me strip this down into popen() form?

After the read_file method, I tried keeping what appeared to do the
actual work but.. no luck.. any suggestions?
#------------------------------------------------------------------------------------------------->
    cmd = 'cmd.exe'
    input = "c:\\temp\\test.bat\nexit\n"
    # create 3 pipes
    child_in_r, child_in_w = create_pipe
    child_out_r, child_out_w = create_pipe
    child_error_r, child_error_w = create_pipe
    # Ensure the write handle to the pipe for STDIN is not inherited.
    set_handle_information(child_in_w, HANDLE_FLAG_INHERIT, 0)
    set_handle_information(child_out_r, HANDLE_FLAG_INHERIT, 0)
    set_handle_information(child_error_r, HANDLE_FLAG_INHERIT, 0)

    processId, threadId = create_process(cmd, child_in_r,
      child_out_w, child_error_w)

# we have to close the handles, so the pipes terminate with the process
    close_handle(child_out_w)
    close_handle(child_error_w)

    write_file(child_in_w, input)
#------------------------------------------------------------------------------------------------->
# while !(buffer = read_file(child_out_r)).empty?
#   edit.appendText(buffer.gsub("\r", ''))
# end

thank you very much!
