Notices
When execution begins, the program break
(the first location beyond the data)
coincides with
end,
but the program break may be reset by
the routines
brk,
malloc,
the standard input/output library
[see
Intro(S)],
by the profile
(-p)
option of
cc,
and so on.
Thus, the current value of the program break
should be determined by
sbrk (0)
[see
brk(S)].
