http://lkml.org/lkml/2009/7/2/78Linux also uses pipes as references of kernel buffers. In that case, only one RW file descriptor will be enough, instead of inventing a new system call, I think extending the existing pipe() is a better idea. If pipe is passed with a NULL pointer, one RW file descriptor is returned. I have checkd the other architectures except of x86, it seems that not all of the platforms implement this system call with the prototype: int pipe(int fd[2]); and changing glibc is needed. Is it possible to extend pipe() in this way? |
