Write а cоde tо implement оrdinаry pipes between а parent and a child to implement bi-directional full duplex communication between a parent and a child. You may use the code from the class to start attached below. You can use only one buffer for the parent and one for the child for the full duplex communication. (50 points) The parent first writes and the child reads the data, Next the child writes something and the parent reads the data. As mentioned earlier there will be a single buffer for the parent called msg_parent and a single buffer for the child called msg_child. So after the parent writes you may want to clear the parent's buffer by using memset function. Here is how memset works. Likewise you may want to do the same for the child's buffer. You may use strcpy to copy the text to the buffers than assigning any fixed string like char write msg[BUFFER SIZE] = "Greetings"; #include #include int main () { char str[50]; strcpy(str,"This is string.h library function"); puts(str); memset(str,'$',7); //the str will be set to $$$$$$$ puts(str); return(0); } void *memset(void *str, int c, size_t n) where str − This is a pointer to the block of memory to fill. c − This is the value to be set. The value is passed as an int, but the function fills the block of memory using the unsigned char conversion of this value. n − This is the number of bytes to be set to the value. sample output: (a.out is the executable) I have bolded the output segment to show the messages that I want you to exchange between parent and child. Also your output should look like the following. madhurima@madhurima-virtual-machine:~/Desktop/CMPSC473/final-src-osc10e_modified/ch3$ ./a.out Parent Writes - Greeting from ParentChild read from parent - Greeting from ParentChild Writes - Greeting back!Parent read from the child the message - Greeting back!The parent is about is leave where the child already left #include #include #include #include #define BUFFER SIZE 25 #define READ END 0 #define WRITE END 1 int main(void) { char write msg[BUFFER SIZE] = "Greetings"; char read msg[BUFFER SIZE]; int fd[2]; pid t pid; /* create the pipe */ if (pipe(fd) == -1) { fprintf(stderr,"Pipe failed"); return 1; } /* fork a child process */ pid = fork(); if (pid < 0) { /* error occurred */ fprintf(stderr, "Fork Failed"); return 1; } if (pid > 0) { /* parent process */ /* close the unused end of the pipe */ close(fd[READ END]); /* write to the pipe */ write(fd[WRITE END], write msg, strlen(write msg)+1); /* close the write end of the pipe */ close(fd[WRITE END]); }else { /* child process */ /* close the unused end of the pipe */ close(fd[WRITE END]); /* read from the pipe */ read(fd[READ END], read msg, BUFFER SIZE); printf("read %s",read msg); /* close the read end of the pipe */ close(fd[READ END]);}return 0;}
