Write two AWK scripts (i.e. 'count_alloc.awk' and 'list_sizes.awk') to run on the malloc.txt file.
- count_allocs.awk
- write an awk script count_allocs.awk that counts the number of successful allocs and the number of failed alloc calls. Your program should act like this:
-
$ awk -f count_allocs.awk malloc-out.txt
num successes: 448; num failures: 106
-
- write an awk script count_allocs.awk that counts the number of successful allocs and the number of failed alloc calls. Your program should act like this:
- list_sizes.awk
- write an awk script list_sizes.awk that prints the size of every element in the free list, in order, after each Free or Alloc operation. Your program should act like this:
-
$ awk -f list_sizes.awk malloc-out.txt | head
