Function sdl2_sys::SDL_GetNumRenderDrivers

pub unsafe extern "C" fn SDL_GetNumRenderDrivers() -> c_int

Get the number of 2D rendering drivers available for the current display.

A render driver is a set of code that handles rendering and texture management on a particular display. Normally there is only one, but some drivers may have several available with different capabilities.

There may be none if SDL was compiled without render support.

\returns a number >= 0 on success or a negative error code on failure; call SDL_GetError() for more information.

\since This function is available since SDL 2.0.0.
