What I have done so far is a little program that looks like this:

include <stdio.h>
main...
{
char *s;
while(1)
{gets(s);
printf(">>%s",s)}
}


And I start it with gets|backend.exe

this works fine, the program can read the output from backend.exe fine,
and print it out correct.

Now, I would not like to use the "pipe" to start it, and a solution
would be to have another program that is little less than

main...
{
start_dos_program("gets.exe|backend.exe")
}

What my question essentially was, were:

what is the name and sysntax of START_DOS_PROGRAM ?, which I have
gotten some hints on, and also:

 can I somehow get rid of the extra program that starts the piped two
programs, that would be fine since t would save me one executable or
one .bat file. The caller program must continue to execute and NOT wait
until the backend has terminated.

I am almost there now, but if someone could help me a little further it
would be much appreciated.
