It was (is?) a gnu C (and probably C++) extension that acted (acts?)
similarly to the ternary operator.
a >? b --> (a > b ? a : b)
a <? b --> (a < b ? a : b)

Please do not top-post.
expr1 ? expr2 : expr3 returns expr2 if expr1 is true, and expr3
>> a >? b --> (a > b ? a : b)
returns a if a is greater than b, and b otherwise, i.e. the same as
>> a <? b --> (a < b ? a : b)
returns the same as std::min(a,b).
