i trying find way count number of processes created in loop of length 10 fork() call. easy see result 2^n n calls, need way compute in program. i have found identical question in here . however, when tested second solution given here, works ok number of forks less 10. 10, yelds 256. why that? , there solution problem? (apart using pipes). here actual code: for(i=1; i<=10; i++) { fork(); printf("the process pid=%d\n", getpid()); } there 1 byte exit status of process. therefore, cannot count higher 255 via process exit codes. furthermore, quirk of specific algorithm tried happens produce maximum possible exit status (to parent process adds 1 256 ). exit() function uses least significant 8 bits of argument (and returning x main() has same effect calling exit(x) ). to count higher, need different approach. establish counter in shared memory, , have each child process increment (with appropriate synchronization). runs cleanly, shared memory n...
