What is wrong with the following code, there is no result ,just waiting, i do not know why that happens
Code:int main(void) { int pid, mypipe[2]; if(pipe(mypipe) == -1) { perror("pipe"); exit(1); } pid = fork(); if(pid > 0) { dup2(mypipe[0],0); close(mypipe[0]); execlp("wc","wc",NULL); perror("exec"); exit(1); } if(pid == 0) { dup2(mypipe[1],1); close(mypipe[1]); execlp("ls", "ls", NULL); perror("exec"); exit(1); } return 0; }
