Tom,
    Thanks for your help, first.
The situation is, I am writing a UI and want to show a C program running
results. Everything is ok but the interactive mode of that C program. I
integrate the C program with a vprocess, first, I transfer a command string
(init = v.exe + interactive_option) than input this string to the vprocess,
I really get the first step of the result, now I don't know whether the
vprocess is alive or not, than I type the second_command at a shell, but it
show nothing on the screen.
>....(results of first step)
>second_command

Should I use a pipe or other method to reach the purpose? Thank you for your
help and I hope you can tell me something to do.
Kevin
