how to read from /dev/ as a stream ?

Hello,...

i wish to use /dev/video (or /dev/dsp) as a stream and work with it:
for the basic i wish only to get hold of data and manipulate it
i tried the next :

Code:

---

include <stdio.h>

int main(int argc,char **argv)
{
       
        fclose(stdin);
       
        fopen("/dev/dsp","r");
        while(1)
        {
                putchar(getchar());
        }
        fclose(stdin);
        return 0;
}

---

i wish to "see" the what is sent to the audio transfer (or any other).
the problem is that i get all the time the same character (i guess it is 0).

in the end i wish to be able to copy a stream (audio and video) and transfer and transfer it over the network to other pc and there to the correct devices :
pc1/dev/video1 -> pc2/dev/video1
pc1/dev/dsp -> pc2/dev/video1

Well you've closed stdin, and not assigned the result of fopen() to anything.

Try freopen()
