SDL_NS_TO_US(3) SDL3 FUNCTIONS SDL_NS_TO_US(3)

SDL_NS_TO_US - Convert nanoseconds to microseconds.

Defined in SDL3/SDL_timer.h

#include "SDL3/SDL.h"
#define SDL_NS_TO_US(NS)        ((NS) / SDL_NS_PER_US)

This performs a division, so the results can be dramatically different if NS is an integer or floating point value.

Returns NS, expressed in microseconds.

It is safe to call this macro from any thread.

This macro is available since SDL 3.2.0.
