Applied with a minor change: instead of inventing
Page PageGetTempPage(Page page, bool copy)
I split it into two functions
Page PageGetTempPage(Page page)
Page PageGetTempPageCopy(Page page)
I don't see any advantage to having the single function, because it
doesn't seem like any calling code path would be likely to want both
behaviors depending on some condition. Moreover, the way you had it
meant that we'd be replacing
Page PageGetTempPage(Page page, Size specialSize);
with
Page PageGetTempPage(Page page, bool copy);
which seems risky to me. If someone failed to update code that was
meant to call the old API, they'd get no warning about it --- at least
not in any C compiler I'm familiar with. Changing the number of
arguments guarantees a compile error for un-updated code.
