following program shared memory implementation parent , child processes use shared memory printing next alphabet given parent. there shared memory , both processes attaching obtain required result. in code, parent process not execute @ all. #include<stdio.h> #include<stdlib.h> #include<unistd.h> #include<string.h> #include<sys/ipc.h> #include<sys/shm.h> #include<sys/types.h> int main(int argc,char *argv[]) { int smid; pid_t x; char *sm; smid=shmget(ipc_private,(size_t)sizeof(char),ipc_creat); x=fork(); if(x>0) { sm=(char *)shmat(smid,null,0); sprintf(sm,"%s",argv[1]); printf("parent wrote:\n"); puts(sm); sleep(4); printf("parent got:\n"); puts(sm); shmdt(sm); shmctl(smid,ipc_rmid,null); } else if(x==0) { sleep(2); sm=(char *)shmat(smid,null,0); printf("child read:\n"); puts(sm); sm[0]++; } retur...

this pretty follow-up last question ( clojure idiomatic way update multiple values of map ), not quite same. (keep in mind i'm new clojure , functional languages alike) suppose have following data structure, defined map of sets: (def m1 {:1 #{2} :2 #{1 3} :3 #{1}}) and map of maps such: (def m2 {:1 {:1 0 :2 12 :3 23} :2 {:1 23 :2 0 :3 4} :3 {:1 2 :2 4 :3 0}}) what want update registries of m2 have correspondence in m1 value. let's value want x . resulting m2 this: {:1 {:1 0 :2 x :3 23} :2 {:1 x :2 0 :3 x} :3 {:1 x :2 4 :3 0}} assuming v contains every possible key map, y first attempt, (that failed miserably) this: (assume x=1 (for [i v] reduce (fn [m j] (assoc-in m [i j] 1)) d (i m1))) needless failure. so, how idiomatic way this? as understand requirements want to produce number of key-sequences m1 . in m2 associate each of key-sequences particular constant value. the first step simple transformation of m1 . want produce 0 or more ke...
