Detecting if a push button was pressed and releasereleased

I want to detect if a push button was pressed and released again. So I thought the right approach would be to first wait while the pin yields LOW and then wait while the pin yields HIGH:

void push(int pin) {
  // wait until button was pushed down...
  while (digitalRead(pin) == LOW);
  // ... and released again
  while (digitalRead(pin) == HIGH);
}

That function can be easily reused. The code works fine, but I am just wondering if that solution is considered clean and a good practice.
