SDL_GetCameraPermissionState - Man Page

Defined in SDL3/SDL_camera.h

#include "SDL3/SDL.h"

int SDL_GetCameraPermissionState(SDL_Camera *camera);

Cameras will not function between when the device is opened by the app and when the user permits access to the hardware. On some platforms, this presents as a popup dialog where the user has to explicitly approve access; on others the approval might be implicit and not alert the user at all.

This function can be used to check the status of that approval. It will return 0 if still waiting for user response, 1 if the camera is approved for use, and -1 if the user denied access.

Instead of polling with this function, you can wait for a

SDL_EVENT_CAMERA_DEVICE_APPROVED
(or

SDL_EVENT_CAMERA_DEVICE_DENIED ) event in the standard SDL event loop, which is guaranteed to be sent once when permission to use the camera is decided.

If a camera is declined, there's nothing to be done but call

SDL_CloseCamera () to dispose of it.

camera

the opened camera device to query.

Returns -1 if user denied access to the camera, 1 if user approved access, 0 if no decision has been made yet.

It is safe to call this function from any thread.

This function is available since SDL 3.2.0.
