Yes, you make a SYS$RELEASE_SEGMENT call.

No, actually, you call sbrk.

No, no, no, the *right* way is to . . .   :-)

The words `operating system' are a bit hint: this question belongs on
an O/S specific newsgroup (preferably one for the O/S in question).

Note that there is usually no reason malloc() cannot be coded to give
space back to the O/S, but it is sometimes tricky to get this right.
