SDL_GetNumAudioDrivers - Man Page
Use this function to get the number of built-in audio drivers.
Header File
Defined in SDL3/SDL_audio.h
Synopsis
#include "SDL3/SDL.h" int SDL_GetNumAudioDrivers(void);
Description
This function returns a hardcoded number. This never returns a negative value; if there are no drivers compiled into this build of SDL, this function returns zero. The presence of a driver in this list does not mean it will function, it just means SDL is capable of interacting with that interface. For example, a build of SDL might have esound support, but if there's no esound server available, SDL's esound driver would fail if used.
By default, SDL tries all drivers, in its preferred order, until one is found to be usable.
Return Value
Returns the number of built-in audio drivers.
Thread Safety
It is safe to call this function from any thread.
Availability
This function is available since SDL 3.2.0.
