NAME

SDL_GetNumCameraDrivers - Use this function to get the number of built-in camera drivers.

HEADER FILE

Defined in SDL3/SDL_camera.h

SYNOPSIS

#include "SDL3/SDL.h"

int SDL_GetNumCameraDrivers(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 v4l2 support, but if there’s no kernel support available, SDL’s v4l2 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 camera drivers.

THREAD SAFETY

It is safe to call this function from any thread.

AVAILABILITY

This function is available since SDL 3.2.0.
