SDL_GetNumAudioDrivers
Use this function to get the number of built-in audio drivers.
Syntax
int SDL_GetNumAudioDrivers(void)
Return Value
Returns the number of built-in audio drivers.
Code Examples
int i;
for (i = 0; i < SDL_GetNumAudioDrivers(); ++i) {
printf("Audio driver %d: %s\n", i, SDL_GetAudioDriver(i));
}
Remarks
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.
Version
This function is available since SDL 2.0.0.
