Не поленился на Си проверить, работает:
Код | #include <stdio.h> #include <unistd.h> #include <sys/types.h>
int main(void) { int fd[2], nbytes; pid_t childpid; char string[] = "Hello, world!\n"; char readbuffer[80];
pipe(fd); if((childpid = fork()) == -1) { perror("fork"); exit(1); }
if(childpid == 0) { /* Child process closes up input side of pipe */ close(fd[0]);
/* Send "string" through the output side of pipe */ for (;;) { write(fd[1], string, (strlen(string)+1)); sleep(1); } exit(0); } else { /* Parent process closes up output side of pipe */ close(fd[1]);
/* Read in a string from the pipe */ for (;;) { nbytes = read(fd[0], readbuffer, sizeof(readbuffer)); printf("Received string: %s", readbuffer); } } return(0); }

Чем для python такая конструкция особенная.... |
