Function SDL_GetCameraDriver 

pub unsafe extern "C" fn SDL_GetCameraDriver(
    index: c_int,
) -> *const c_char

Use this function to get the name of a built in camera driver.

The list of camera drivers is given in the order that they are normally initialized by default; the drivers that seem more reasonable to choose first (as far as the SDL developers believe) are earlier in the list.

The names of drivers are all simple, low-ASCII identifiers, like “v4l2”, “coremedia” or “android”. These never have Unicode characters, and are not meant to be proper names.

Parameters

• index: the index of the camera driver; the value ranges from 0 to SDL_GetNumCameraDrivers() - 1.

Return value

Returns the name of the camera driver at the requested index, or NULL if an invalid index was specified.

Thread safety

It is safe to call this function from any thread.

Availability

This function is available since SDL 3.2.0.
