    how to read from /dev/ as a stream ?


    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 :
    include <stdio.h>
    int main(int argc,char **argv)
            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()
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
