Question regarding srand48 and time(null)

Question

srand48((long int) atoi(argv[2])); Does this mean that srand48 will seed using a long and an int? }

else

{ srand48((long int) time(NULL)); returns the number of seconds since epoch.. so basically time elapse?????

yes. long int is basically a longer version of int

srand48((long int) time(NULL)); returns the number of seconds since epoch.. so basically time elapse?????

time(null) is now and epoch (Jan 1, 1970). So it is the time elapse from epoch to the current time
