inline size_t carb::audio::decrementWithWrap(size_t counter, size_t modulo)

Decrement a counter with a non-power-of-2 modulo.


This function exists to perform a modulo around a non-power-of-2 modulo without having to duplicate the wrap code in multiple places. Note that % does not work for decrementing with a non-power-of-2 modulo.

  • counter[in] The counter value to increment. This must be less than or equal to modulo. counter == modulo is allowed for some edge cases where it’s useful.

  • modulo[in] The value to perform a modulo by. This may not be 0.


counter incremented and wrapped around modulo.
