People could be tempted to borrow this formula and apply to situations where
it doesn't fit.
Normally one uses
#define CEIL(a,b) (((a) + (b) - 1) / (b))
but not here, because here
- this formula could yield overflow,
- it is known that dkLen > 0.

The comment already explains it:
l = CEIL (dkLen / hLen) ,
But you are free to add more comments, of course.
