SDL_GL_SetSwapInterval - Set the swap interval for the current OpenGL context.
Defined in SDL3/SDL_video.h
#include "SDL3/SDL.h"
bool SDL_GL_SetSwapInterval(int interval);
Some systems allow specifying -1 for the interval, to enable adaptive vsync. Adaptive vsync works the same as vsync, but if you've already missed the vertical retrace for a given frame, it swaps buffers immediately, which might be less jarring for the user during occasional framerate drops. If an application requests adaptive vsync and the system does not support it, this function will fail and return false. In such a case, you should probably retry the call with 1 for the interval.
Adaptive vsync is implemented for some glX drivers with GLX_EXT_swap_control_tear, and for some Windows drivers with WGL_EXT_swap_control_tear.

Returns true on success or false on failure; call
SDL_GetError () for more information.
This function should only be called on the main thread.
This function is available since SDL 3.2.0.
