◆ ternary_compare()

int ternary_compare ( const QDateTime &  a,
const QDateTime &  b 

balanced ternary (three way) comparison This is equivalent to C++20's operator <=>.

See also ternarycompare.h.

Less than means earlier and greater than means later.

Since Qt 5.14 invalid QDateTimes compare equal and are less than all valid QDateTimes.
