Using pipes running apps

[kovitch]

Hi,

I am trying to run a command line program (in windows), so I use the following code:

FILE *cmd_pipe;
cmd_pipe = popen ("WaveRecorder.exe temp.wav", "r");
pclose (cmd_pipe);

Now, I have a problem, my WaveRecorder stops when I press Enter key.

Is there a way to simulate "Enter" into the pipe? Is it possible to write more than one command into the pipe?

Command line programs which wait for the enter key are just waiting for the newline charicter "\n". You should be able to simply write that charicter to the pipe.

fputc('\n', cmd_pipe);

Notice the single quotes here not double quotes.

Hope this helps
