NAME

       SDL_GetCameraPermissionState - Query if camera access has been approved by the user.

SYNOPSIS

       #include <SDL3/SDL_camera.h>

       int SDL_GetCameraPermissionState(SDL_Camera *camera);

DESCRIPTION

       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.

FUNCTION PARAMETERS

       camera the opened camera device to query.

RETURN VALUE

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

THREAD SAFETY

       It is safe to call this function from any thread.

AVAILABILITY

       This function is available since SDL 3.2.0.
