NAME¶
SDL_GL_GetSwapInterval - Get the swap interval for the current OpenGL context.
SYNOPSIS¶
#include <SDL3/SDL_video.h>

DESCRIPTION¶

FUNCTION PARAMETERS¶
- interval
- output interval value. 0 if there is no vertical retrace synchronization, 1 if the buffer swap is synchronized with the vertical retrace, and -1 if late swaps happen immediately instead of waiting for the next retrace.
RETURN VALUE¶
Returns true on success or false on failure; call SDL_GetError() for more information.
THREAD SAFETY¶
